PROPOSAL ELECTION OF DIRECTORS The By-laws of the Company provide that the Company have a Board of Directors of not less than five or more than nine directors, with the number of directors to be fixed by the Board from time to time. The number of directors is presently fixed at eight. Directors serve until the next annual meeting and until their respective successors have been elected and qualified. The Board of Directors currently consists of eight directors. One incumbent director, Gary D. Penisten, has decided to retire from the Board of Directors at the conclusion of his present term as director, and accordingly, he will not stand for reelection. His term as a director will expire at the Meeting; at that time the number of directors will be fixed at seven. Seven directors are to be elected at the Meeting to serve for one-year terms until the 2009 Annual Meeting of Shareholders and until their respective successors are elected and qualified. The Board has determined to nominate seven individuals for election to the Board of Directors, each of whom is presently an incumbent director. The Board of Directors knows of no reason why any nominee would be unable to serve as director. Each nominee has consented to being named as a nominee for director of the Company in this Proxy Statement and to serve as a director if elected. If any nominee should for any reason become unable to serve, then all valid proxies will be voted for the election of a substitute nominee designated by the Board.

All Directors attended at least 75% of the aggregate of the total number of the Board meetings and meetings of committees of the Board of which they were a member. The Board of Directors has established standing Executive, Audit, and Compensation Committees, each of which is comprised solely of independent non-employee members of the Board of Directors. The Board of Directors does not have a standing Nominating Committee. INDEPENDENCE DETERMINATIONS The Board of Directors annually determines the independence of directors. No director is considered independent unless the Board has determined that he or she has no material relationship with the Company, either directly or as a partner, shareholder, or officer of an organization that has a material relationship with the Company or otherwise. Material relationships can include commercial, banking, consulting, legal, accounting, charitable, and familial relationships, among others. Independent directors are directors who, in the view of the Board of Directors, are free of any relationship that would interfere with the exercise of independent judgment. Under American Stock Exchange rules, the following persons shall not be considered independent: (a) a director who is or was employed by the Company or any of its affiliates for the current year or any of the past three years; (b) a director who accepted or who has an immediate family member who accepted any compensation from the Company or any of its affiliates in excess of $100,000 during any period of twelve consecutive months within the three years preceding the determination of independence (other than certain specified types of compensation, including, e.g., compensation for Board or Committee service, benefits under a tax-qualified retirement plan, or non-discretionary compensation); (5)

(c) a director who is a member of the immediate family of an individual who is, or has been in any of the past three years, employed by the Company as an executive officer; (d) a director who is, or has an immediate family member who is, a partner in, or a controlling shareholder or an executive officer of, any organization to which the Company made, or from which the Company received payments (other than those arising solely from investments in the Company's securities) that exceed 5% of the organization's consolidated gross revenues for that year, or $200,000, whichever is more, in any of the past three years; (e) a director who is, or has an immediate family member who is employed as an executive of another entity where at any time during the most recent three fiscal years, any of the Company's executive officers serve on that other entity's compensation committee; and (f) a director who is, or has an immediate family member who is, a current partner of the Company's outside auditor, or was a partner or employee of the Company's outside auditor who worked on the Company's audit at any time during any of the past three years. Immediate family includes a person's spouse, parents, children, sibling, mother-in-law, father-in-law, brother-in-law, sister-in-law, son-in-law, daughter-in-law, and anyone who resides in such person's home. Mr. Johnsen, Chairman of the Board, serves as Chief Executive Officer of the Company, and Mr. Olschan, a member of the Board, serves as President and Chief Operating Officer of the Company. The Board has determined that all of the other current directors are "independent" within the meaning of the applicable listing standards of the American Stock Exchange. These independent directors are: Mr. Davidson, Mr. Holden, Ms. Murphy, Mr. Spinelli and Mr. Ward, each of whom is standing for reelection, and Mr. Penisten, who is not standing for reelection. EXECUTIVE COMMITTEE The Executive Committee of the Board of Directors is composed of Mr. Penisten, who serves as Chairman, and Mr. Holden. The function of the Executive Committee is to act for the Board of Directors during the intervals between meetings of the Board. The Executive Committee held one meeting in 2007. AUDIT COMMITTEE The Audit Committee assists the Board of Directors in overseeing (1) the audit and integrity of our financial statements, (2) the performance of our independent auditors, (3) the adequacy and effectiveness of our accounting, auditing and financial reporting processes, and (4) our compliance with legal and regulatory requirements. The duties of the Audit Committee include the selection and appointment of our independent auditors, including evaluation of their qualifications, performance and independence. The Board of Directors has determined that all members of the Audit Committee are "independent" and "financially literate" within the meaning of the applicable listing standards of the American Stock Exchange. In addition, the Board has determined that Mr. Ward qualifies as an "audit committee financial expert" within the meaning of regulations adopted by the Securities and Exchange Commission and has the financial sophistication required under the listing standards of the American Stock Exchange. (6)

The Committee consists of Mr. Ward, Chairman, and Messrs. Holden and Spinelli. The Audit Committee meets at least quarterly, and more often as needed. The Committee met six times in 2007. The Board of Directors has adopted a written charter for the Audit Committee, which is reviewed annually by the Audit Committee. A copy of the Audit Committee charter is available on the company's website at www.acmeunited.com in the Investor Relations/Corporate Governance section. NOMINATIONS FOR DIRECTORS The functions of the Nominating Committee are performed by the whole Board. Board of Director nominations are recommended for the entire Board's selection by a majority of the Board's "independent directors," as such term is defined in Section 121A of the American Stock Exchange's listing standards. The Board will consider nominees for directors recommended in writing by shareholders to the Board at least sixty (60) days prior to the annual meeting at which the election of directors is to be held (subject to certain requirements set forth in the By-laws). The nomination should be sent in care of the Secretary of the Company at 60 Round Hill Road, Fairfield, CT 06824, and should include the name, address, telephone number and resume of the nominee's business and educational background, along with a written statement by the shareholder as to why such person should be considered for election to the Board of Directors. The Board follows the same evaluation procedures whether a candidate is recommended by directors or shareholders. In identifying and evaluating nominees for director, the Board considers whether the candidate has the highest ethical standards and integrity, and sufficient education, experience and skills necessary to understand and wisely act upon the complex issues that arise in managing a publicly held company. The Board commences its evaluation of candidates on the basis of materials submitted by or on behalf of the candidate and on the basis of the knowledge of members of the Board and management regarding the candidate. To the extent the Board does not have enough information to evaluate a candidate, the Board may send a questionnaire to the candidate for completion in enough time for Board consideration. In addition, it has historically been customary for some members of the Board to meet with the candidate individually or in small groups. COMPENSATION COMMITTEE The Compensation Committee of the Board of Directors assists the Board in establishing the compensation policies for cash and equity compensation of our executive officers. The duties of the Committee include evaluating and making recommendations to the Board regarding the compensation and equity incentives and awards for our executive officers and the administration of the Company's Non-Salaried Director Stock Option Plan. The Board of Directors has determined that all members of the Compensation Committee are "independent" within the meaning of the applicable listing standards of the American Stock Exchange. The Committee consists of Mr. Holden, Chairman, Messrs. Davidson and Penisten, and Ms. Murphy. The Committee held three meetings during 2007. (7)

The Compensation Committee makes recommendations to the Board of Directors regarding compensation of our executive officers. In 2007, the compensation and benefits for our executive officers consisted of four components: (i) base salary; (ii) a cash incentive bonus award; (iii) stock option awards; and (iv) a benefits package. The base salaries for our officers are set annually and reflect skills and experience, level and scope of responsibility and performance during the prior year and historical, long-term performance. The Compensation Committee also considers external factors, such as cost of living in the areas in which our officers reside and current market conditions. During 2007 the Chief Executive Officer participated in discussions with the Committee regarding the base salary amounts of the executive officers. The Company grants cash incentive awards under our Cash Bonus Plan based upon the achievement of both Company and individual performance objectives. The Company generally makes cash awards under this Plan if the Company achieves the minimum level of net income set for the applicable year. However, the Company may make awards at its discretion if the minimum levels of net income are not attained due to unusual circumstances, but where the performance of individual executive officers merit such awards. During 2007, the Chief Executive Officer proposed bonus awards and reviewed the proposals, and the basis for the proposals, with the Compensation Committee. The Committee subsequently proposed bonus awards to the independent directors of the full Board for final review and approval. The Company's stock option program is administered by the Board of Directors, which acts upon recommendations of the Compensation Committee. The purpose of the Company's stock option program is to facilitate the acquisition of equity interests in the Company by its officers and key employees and thus their sharing in the future success of the Company's business. The Committee takes into account factors such as: (i) the total number of shares of common stock outstanding; (ii) the total number of shares of common stock which remain available for grant under the Company's various stock option plans; and (iii) the need to have an appropriate balance between currently paid and longer-term compensation, and between cash and equity compensation. COMPENSATION OF DIRECTORS DIRECTORS' CASH FEES CASH COMPENSATION As described below, in 2007 the Company paid as compensation to non-employee directors cash consisting of annual fees and fees for Board and committee meetings attended. The Chairman Emeritus of the Board and each director who chaired a committee received additional compensation to compensate for the additional responsibility and effort associated with the director's respective position. These fees consisted of: (8)

o an annual fee of $14,000, payable quarterly; o $1,000 for each Board meeting attended; o $2,000 paid to the Chairman Emeritus of the Board for each Board meeting; o $600 for each committee meeting attended; o $600 to the committee chairpersons for each committee meeting conducted; and o an annual fee of $3,200 to the Chairperson of the Audit Committee. In addition, the Company provided reimbursement to each director for customary and usual travel expenses incurred in connection with attendance at Board and committee meetings. DIRECTORS' STOCK OPTIONS On April 23, 2007, the date of the last annual meeting of shareholders, each non-employee director re-elected to the Board of Directors received an annual option grant, as provided under the 2005 Non-Salaried Director Stock Option Plan, to purchase 2,500 shares of Common Stock. Each option had an exercise price of $14.51 per share, and was immediately exercisable in full. Under the Non-Salaried Director Stock Option Plan, each new director, upon becoming a member of the Board of Directors, receives an option to purchase 5,000 shares of Common Stock. These options vest as follows: 25% on the day after the date of the grant; 25% one day after the first year anniversary of the date of grant; 25% one day after the second year anniversary of the date of grant; and 25% one day after the third year anniversary of the date of grant. ATTENDANCE AT ANNUAL MEETINGS While the Company has no formal policy regarding the attendance of Board members at annual meetings of shareholders, director attendance is deemed very important and is strongly encouraged. In 2007, all eight then incumbent members of the Board attended the 2007 Annual Meeting of Shareholders. SHAREHOLDER COMMUNICATIONS WITH DIRECTORS The Company has established a process for shareholders to send communications to the Board of Directors. Shareholders may send communications to the Board of Directors to the attention of the Secretary, Acme United Corporation, 60 Round Hill Road, Fairfield, Connecticut 06824, who will forward them to all Board members within a reasonable time after receipt. If the shareholder wishes the communication to be sent to one or more specific Board members only, the addressee should be the specific Board member(s), "c/o Secretary", who will then forward the communication to such Board member(s). If one or more specific Board members are not designated for such other communication, the communication will be forwarded to the entire Board. (9)

The deferral may be for all or a portion of the participant's Cash Bonus Plan.

PENSION BENEFITS In December 1995, the Board of directors adopted a resolution to freeze the Retirement Plan resulting in no further benefit accruals after February 1, 1996. None of the NEOs is a participant of the Pension Plan. CHANGE IN CONTROL ARRANGEMENTS--SALARY CONTINUATION PLAN The Company has a Salary Continuation Plan that covers officers of the Company at the level of Corporate Vice President or above, under the age of sixty-five (65). The Plan is designed to retain key employees and provide for continuity of management in the event of an actual or threatened change in control of the Company. A covered officer would receive payment under the Plan if there is a disposition of the Company and, within one year (or if such employee is also a director, within two years) after such change in control, one of the following triggering events occurs: o involuntary termination; o a reduction in responsibility, status or compensation; o transfer to a location unreasonably distant from his or her current location; or o voluntary resignation. A disposition of the Company shall include (i) a sale of substantially all the assets of the Company or a successor, or of a Division with more than 50% of the sales of the Company in the preceding full year of operations, such that shareholder approval is required and (ii) the acquisition by any such person or group of persons acting in concert, of legal or beneficial ownership of fifty percent (50%) or more of the voting stock of the Company, or its successor. The compensation provided to a covered officer upon disposition of the Company would consist of the following: o monthly salary rate being paid at the date of the change in control multiplied by the number of months payable; o average monthly incentive bonus payments for the prior three taxable years multiplied by the number of months payable; and o medical, life and other insurance in effect at the date of disposition to continue into the future for the number of months compensation is payable. Payment of the first two items would be in a lump sum, payable no later than thirty (30) days after the date on which the officer submits notice to the Board that the officer wishes to exercise his or her rights under the Plan. A Director of the Company who is also an officer of the Company at the level of Executive Vice President or above would be entitled to the value of thirty-six (36) months' compensation and benefits for thirty-six (36) months. Officers at the level of Senior Vice President and Vice President would be entitled to the value of twenty-four (24) months' compensation and benefits for twenty-four (24) months. The Plan presently covers Walter C. Johnsen, Brian S. Olschan, Larry H. Buchtmann and Paul G. Driscoll. Walter C. Johnsen and Brian S. Olschan would be entitled to the value of thirty-six (36) months of compensation and benefits. Larry H. Buchtmann and Paul G. Driscoll would be entitled to the value of twenty-four (24) months of compensation and benefits. (14)

SEVERANCE PAY PLAN The Severance Pay Plan covers officers of the Company employed in the United States at the level of Corporate Vice President or above, under the age of sixty-five (65). The Plan is designed to enable the Company to attract and retain key employees. A covered officer would receive payments under the Plan if one of the following triggering events occurs: o involuntary termination for any reason other than gross misconduct; o death; o reduction of responsibility, status or compensation reduced; or o transfer to a location unreasonably distant from his or her current location. This Plan would only apply if the Salary Continuation Plan would not apply. Payment under this Plan, except in the event of termination by death, would be equivalent to one month's salary multiplied by each year of service to the Company based upon the level of his or her compensation in effect immediately preceding such termination. The Plan sets out a minimum and maximum number of months' compensation payable to each such employee upon such severance. The Plan would also provide death benefits to covered officers' beneficiaries. A Director of the Company who is also an Officer of the Company at the level of Executive Vice President or above would be entitled to a minimum of nine (9) months' compensation and a maximum of thirty (30) months' compensation. In the event of such officer's death, his or her beneficiaries would be entitled to nine (9) months' compensation. Officers at the level of Senior Vice President or Vice President would be entitled to a minimum of six (6) months' compensation and a maximum of eighteen (18) months' compensation. In the event of such officer's death, his or her beneficiaries would be entitled to six (6) months' compensation. Payments would be made in a single lump sum. This Plan covers Walter C. Johnsen, Brian S. Olschan, Larry H. Buchtmann and Paul G. Driscoll. Walter C. Johnsen and Brian S. Olschan would be entitled to a minimum of nine (9) months' compensation and a maximum of thirty (30) months' compensation. Larry H. Buchtmann and Paul G. Driscoll would be entitled to a minimum of six (6) months' compensation and a maximum of eighteen (18) months' compensation. In the event of termination by death, beneficiaries of Walter C. Johnsen and Brian S. Olschan would be entitled to a minimum of nine (9) months' compensation and beneficiaries of Larry H. Buchtmann and Paul G. Driscoll would be entitled to a minimum of six (6) months' compensation. (15)

REPORT OF THE AUDIT COMMITTEE The Audit Committee oversees the Company's financial reporting process on behalf of the Board of Directors. The Audit Committee has reviewed and discussed our audited consolidated financial statements for the year ended December 31, 2007, with management and with representatives of Ernst & Young LLP, our independent auditors, including a discussion of the applicability and quality of accounting principles, the reasonableness of significant judgments and the clarity of disclosures in the financial statements. Management has the primary responsibility for the financial statements and our accounting, auditing and financial reporting processes. The Audit Committee is not providing any expert or special assurance as to our financial statements. Ernst & Young LLP is responsible for expressing an opinion on the conformity of our financial statements with generally accepted accounting principles in the United States. The Audit Committee is not providing any professional certification as to Ernst & Young's work product. The Audit Committee has discussed with representatives of Ernst & Young the matters required to be discussed by Statement on Auditing Standards No. 61 (Communication with Audit Committees). The Audit Committee has received and reviewed the written disclosures and letter from Ernst & Young required by Independence Standards Board Standard No. 1 (Independence Discussions with Audit Committees), and has discussed the independence of Ernst & Young with representatives of the firm. The Audit Committee discussed with the Company's independent auditors the overall scope and plan for their respective audits. The Audit Committee met with the independent auditors, with and without management present, to discuss the results of their examinations, their evaluations of the Company's internal controls, and the overall quality of the Company's financial reporting. Based on the reviews and discussion referred to above, the Audit Committee recommended to the Board of Directors that our audited consolidated financial statement for the year ended December 31, 2007 be included in our Annual Report on Form 10-K for the year ended December 31, 2007 for filing with the Securities and Exchange Commission. Stevenson E. Ward, III, Chair Richmond Y. Holden, Jr., Member Stephen Spinelli Jr., Member TRANSACTIONS WITH RELATED PERSONS There were no material transactions between the Company and any "related person". The term related person includes any executive officer of the Company, any director or nominee for election as director, any security holder holding more than 5% of the Common Stock of the Company or any immediate family member of any of the foregoing persons. (17)

Policy The Board of Directors has determined that transactions involving the Company and related persons shall be reviewed and approved by the Audit Committee. The Charter of the Audit Committee requires that related person transactions must be reviewed and approved by the Audit Committee of the Board, which consists solely of independent directors. This requirement covers any such transaction and is not limited to transactions which meet the minimum threshold for disclosure in the proxy statement under the relevant rules under the Exchange Act (generally, transactions involving amounts exceeding $120,000 in which a related person has a direct or indirect material interest). Procedures Management or the affected director or executive officer will bring the transaction to the attention of the Audit Committee. The transaction must be approved in advance whenever practicable, and if not practicable, must be reviewed as promptly as practicable. Although the Audit Committee has not adopted formal procedures for the review and approval of transactions with related persons, the Audit Committee will approve the transaction only if it determines that it is in the best interests of the Company. If the Audit Committee were to approve a related party transaction, the Audit Committee would periodically monitor the transaction to ensure that there are no changed circumstances that would render it advisable for the Company to amend or terminate the transaction. COMPLIANCE WITH SECTION 16(A) OF THE SECURITIES EXCHANGE ACT OF 1934 Section 16(a) of the Securities Exchange Act of 1934 ("Exchange Act") requires the Company's directors and executive officers, and persons who own more than 10% of a registered class of the Company Common Stock (collectively referred to herein as "Reporting Persons"), to file with the SEC and the American Stock Exchange initial reports of ownership and reports of changes in ownership of Common Stock and other equity securities of the Company. Reporting Persons are required by the Exchange Act to furnish the Company with copies of all Section 16(a) forms they file. Based solely on review of copies of such forms received by the Company and written representations from Reporting Persons, the Company believes that, during the 2007 fiscal year, all Reporting Persons complied with all applicable filing requirements under Section 16(a). (18)

These services may include audit services, audit-related services, tax services and other services. The Audit Committee has adopted policies and procedures for the pre-approval of services provided by the independent auditors. The policies and procedures provide that management and the independent auditors jointly submit to the Audit Committee a schedule of audit and non-audit services for approval as part of the annual plan for each year. In addition, the policies and procedures provide that the Audit Committee may also pre-approve particular services not in the annual plan on a case-by-case basis. For each proposed service, management must provide a detailed description of the service and the projected fees and costs (or a range of such fees and costs) for the service. (19)

FEES TO AUDITORS Set forth below is a description of the fees for professional audit services rendered by Ernst & Young LLP for the audit of our annual financial statements and review of our interim financial statements for 2007 and 2006, and fees for other services rendered by Ernst & Young LLP for 2007 and 2006. Fee Category Fiscal 2007 Fees Fiscal 2006 Fees - ------------ ---------------------- ---------------------- Audit Fees $231,000 $220,000 Audit Related Fees $ 17,000 $ 21,000 Tax Fees $ 29,000 $ 58,000 ---------------------- ---------------------- Total Fees $277,000 $299,000 ====================== ====================== Audit Related Fees. These fees were for assistance related to the Company's filing of reports with the Securities and Exchange Commission (Form S-8), adoption of new financial reporting pronouncements, and reporting on internal control. Tax Fees. Tax services included tax compliance, tax advice, and tax planning. The Audit Committee has determined that the provision of non-audit services described above is compatible with maintaining Ernst & Young's independence. APPOINTMENT OF AUDITORS The Company's Audit Committee has not yet appointed an independent auditor to audit the financial statements of the Company for the fiscal year ending December 31, 2008 because the Audit Committee is currently reviewing proposed fees for audit and related work to be performed in respect of fiscal year 2008. The Audit Committee is not aware of any disagreements between management and the Company's current auditors regarding accounting principles and their application or otherwise. Representatives of Ernst & Young LLP are expected to be present at the 2008 Annual Meeting with the opportunity to make a statement if they desire to do so and are expected to be available to respond to appropriate questions. The Company knows of no direct or material indirect financial interest in the Company or of any connection with the Company by this accounting firm except the professional relationship between auditor and client.
