NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) Note 1 -- Basis of Presentation In the opinion of management, the accompanying condensed consolidated financial statements include all adjustments necessary to present fairly the financial position, results of operations and cash flows. These adjustments are of a normal, recurring nature. However, the financial statements do not include all of the disclosures normally required by accounting principles generally accepted in the United States of America or those normally made in the Company's annual report on Form 10-K. Please refer to the Company's annual report on Form 10-K for the year ended December 31, 2004 for such disclosures. The condensed consolidated balance sheet as of December 31, 2004 was derived from the audited consolidated balance sheet as of that date. The results of operations for interim periods are not necessarily indicative of the results to be expected for the full year. Note 2 -- Contingencies The Company is involved from time to time in disputes and other litigation in the ordinary course of business, including certain environmental and other matters. The Company presently believes that there will not be a material adverse impact on financial position, results of operations, or liquidity from these matters. Note 3 -- Pension Components of net periodic pension cost are as follows for the periods ended: Three Months Ended Six Months Ended ------------------------- --------------------------- June 30 June 30 June 30 June 30 2005 2004 2005 2004 ----------- ----------- ------------ ------------ Components of net periodic benefit cost: Interest cost $ 53,365 $ 49,727 $ 102,115 $ 99,453 Service cost 8,750 8,750 17,500 17,500 Expected return on plan assets (69,045) (64,281) (130,045) (128,563) Amortization of prior service costs 2,138 2,194 4,388 4,388 Amortization of actuarial gain 17,102 12,399 33,102 24,797 - ----------------------------------------------------------------------------------------------------- $ 12,310 $ 8,789 $ 27,060 $ 17,575 ===================================================================================================== Note 4 -- Accounting for Stock-Based Compensation The Company has elected to adopt only the disclosure provisions of Statement of Financial Accounting Standards No. 123, Accounting for Stock-Based Compensation, and continues to measure costs for its employee stock compensation plans by using the accounting methods prescribed by APB Opinion No. 25, Accounting for Stock Issued to Employees, which allows that no compensation cost be recognized unless the exercise price of the options granted is less than the fair market value of the Company's stock at date of grant. Generally, no stock-based employee compensation cost is reflected in net income, as all options granted had an exercise price equal to the market value of the underlying common stock on the date of grant. The following table illustrates the proforma effect on net income and earnings per share as if the Company had applied the fair value method under SFAS No. 123, Accounting for Stock Based Compensation, to stock-based employee compensation for the periods ended: (7)

The Company also repurchased 146,000 shares of common stock for treasury. The shares were purchased at fair market value, with a total cost to the Company of $2,203,104. Note 6 -- Business Combination On May 28, 2004, the Company purchased Clauss Cutlery, a division of Alco Industries, Inc.. Sales of Clauss products for three and six months ended June 30, 2004 were $196,000. The purchase price was the aggregate value of inventory, trademarks and brand names totaling $446,754. Included in the accompanying Statement of Operations for the three and six months ended June 30, 2005 is the operations of the acquired business. Sales for Clauss products for the three and six months ended June 30, 2005 were $990,000 and $1,750,000, respectively. In accordance with Regulation S-X, proforma information for the six months ended June 30, 2004 is not provided because of the immateriality of the transaction. (8)

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS Item 2. - Results of Operations Forward-Looking Information The Company may from time to time make written or oral "forward-looking statements" including statements contained in this report and in other communications by the Company, which are made in good faith by the Company pursuant to the "safe Harbor" provisions of the Private Securities Litigation Reform Act of 1995. These forward-looking statements include statements of the Company's plans, objectives, expectations, estimates and intentions, which are subject to change based on various important factors (some of which are beyond the Company's control). The following factors, in addition to others not listed, could cause the Company's actual results to differ materially from those expressed in forward looking statements: the strength of the domestic and local economies in which the Company conducts operations, changes in client needs and consumer spending habits, the impact of competition and technological change on the Company, the Company's ability to manage its growth effectively, including its ability to successfully integrate any business which it might acquire, and currency fluctuations. All forward-looking statements in this report are based upon information available to the Company on the date of this report. The Company undertakes no obligation to publicly update or revise any forward-looking statement, whether as a result of new information, future events, or otherwise, except as required by law. Net Sales Traditionally, the Company's sales are stronger in the second and third quarters, and weaker in the first and fourth quarters of the fiscal year due to the seasonal nature of the back-to-school business. Consolidated net sales for the quarter ended June 30, 2005 were $14,904,000 compared with $12,298,000 for the same period in 2004, a 21% increase. Net sales for the first six months of 2005 were $25,487,000 compared with $20,865,000 for the same period in 2004, a 22% increase. Excluding the favorable effect of currency gains in Canada and Europe, the net sales increase represented 20%. The sales increase was mainly driven by a 25% increase in U.S. sales and Hong Kong direct import sales due to market share gains, new product launches and the Clauss business acquired on May 28, 2004. Combined Europe and Canada sales were up 7% in local currency. Gross Profit Gross profit for the second quarter of 2005 was $6,731,000 (45.2% of net sales) compared to $5,519,000 (44.9% of net sales) for the second quarter of 2004. Gross profit for the first six months of 2005 was $11,592,000 (45.5% of net sales compared to $9,239,000 (44.3% of net sales) in the same period of 2004. The increased percentage of new products with higher gross margins coupled with positive impacts from product rationalization efforts and sales of a more profitable product mix in Europe were the main reasons for the improved gross margins. Offsetting factors to the improved margins were increased raw material costs and a higher volume of airfreight costs due to orders of some items in excess of those anticipated. Selling, General and Administrative Expenses Selling, general and administrative ("SG&A") expenses for the second quarter of 2005 were $4,577,000 (31% of net sales) compared with $3,579,000 (29% of net sales) for the same period of 2004, an increase of $998,000. SG&A expenses were 33% of net sales for the first six months of 2004 versus 31% in the comparable period of 2004. The majority of the increase relates to higher sales commission and freight costs associated with increased sales, investment in new products and the addition of sales, marketing, logistics and quality control personnel. (9)

Interest Expense Interest expense for the second quarter of 2005 was $43,000, compared with $40,000 for the same quarter of 2004. Interest expense for the first six months of 2005 was $56,000, compared with $85,000 for the same period of 2004, a $29,000 decrease. This decrease is mainly attributable to the decline in bank debt (the amount outstanding under the Company's revolving credit facility). Other Expense, Net Net other expense was $97,000 in the second quarter of 2005 compared to net other expense of $80,000 in the second quarter of 2004. Net other expense was $146,000 for the first six months of 2005 as compared to $74,000 for the same period of 2004. The change from 2004 is primarily due to higher foreign exchange transaction losses in 2005. Income Before Income Taxes Income before income taxes was $2,014,000 in the second quarter of 2005 compared with $1,820,000 in the second quarter of 2004, an increase of $194,000. Income before income taxes was $3,094,000 for the first six months of 2005 compared with $2,530,000 in the first six months of 2004, an improvement of $564,000. Pretax income for North America and Asia increased by $234,000. The European operations had a net loss of $60,000 in the first six months of 2005 compared to a net loss of $390,000 in the same period of 2004. The results of the European operations are improving due to higher sales, product rationalization efforts and a more profitable product mix. The higher sales are primarily due to increases in the sales force and increased advertising. Income Taxes The effective tax rate in the first six months of 2005 was 37% compared to 42% in 2004. The lower effective tax rate is principally due to lower losses in Europe for which there is no recorded tax benefit because the losses in Europe cannot be utilized to offset earnings in other countries. Net Income Net income for the second quarter of 2005 was $1,314,000, or 34 cents per share (diluted), compared to a net income of $1,075,000, or 29 cents per share (diluted), for the same period of 2004. Net income for the first six months of 2005 was $1,964,000, or 52 cents per share (diluted), compared to a net income of $1,468,000, or 40 cents per share (diluted), for the same period of 2004. (10)

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS-Continued Financial Condition Liquidity and Capital Resources The Company's working capital, current ratio and long-term debt to equity ratio follow: June 30, 2005 December 31, 2004 ---------------------------------- Working capital $ 11,888,952 $ 11,548,693 Current ratio 1.89 2.38 Long term debt to equity ratio 0.4% 0.4% During the first six months of 2005, total debt increased by $3,588,000 compared to total debt at December 31, 2004 principally as a result of the buildup of inventory in anticipation of the Company's stronger sales in the second and third quarters and the repurchase of company stock. During September 2004, the Company renewed its revolving loan agreement, which originally allowed for borrowings up to a maximum of $10,000,000 based on a borrowing base formula, which applied specific percentages to balances of accounts receivable and inventory. The renewal modified several terms of the original agreement, the most significant of which are reducing the interest rate to LIBOR plus 1.50% from LIBOR plus 1.75%, eliminating the borrowing base formula, allowing the Company to borrow up to $10,000,000, regardless of its inventory and receivable levels, and extending the maturity of the loan to June 30, 2007. As of June 30, 2005, $4,967,500 was outstanding and $5,032,500 was available for borrowing under this agreement. The Company anticipates that all debt currently outstanding under this loan agreement will be paid off in 2005. However, the Company may draw down additional funds under this loan agreement in the future. Cash expected to be generated from operating activities, which together with funds available under its existing loan agreement, are expected, under current conditions, to be sufficient to finance the Company's planned operations over the next twelve months. Over that same period, the Company does not expect to make significant investments in property, plant, and equipment. Recently Issued Accounting Standards In December 2004, the Financial Accounting Standards Board ("FASB") issued Statement of Financial Accounting Standards No. 123 (revised 2004) ("SFAS 123 (R)"), "Share-Based Payment", which revised SFAS No. 123, "Accounting for Stock-Based Compensation". This statement supercedes APB Opinion No. 25, "Accounting for Stock Issued to Employees". The revised statement addresses the accounting for share-based payment transactions with employees and other third parties, eliminates the ability to account for share-based compensation transactions using APB 25 and requires that the compensation costs relating to such transactions be recognized in the consolidated statement of operations. The revised statement is effective as of the first annual period beginning after June 15, 2005. Acme will adopt the statement on January 1, 2006 as required. The impact of adoption of SFAS 123 (R) cannot be predicted at this time because it will depend on levels of share-based payments granted in the future. However, had Acme adopted SFAS 123 in prior periods, the impact of that standard would have approximated the impact of Statement 123 as described in the disclosure of pro forma net income and net income per share in the stock-based compensation accounting policy note included in Note 4 to the consolidated financial statements. (11)

In November 2004, the FASB issued SFAS No. 151, "Inventory Costs, an amendment of ARB No. 43, Chapter 4," to clarify that abnormal amounts of idle facility expense, freight, handling costs and wasted material (spoilage) should be recognized as current period charges, and that fixed production overheads should be allocated to inventory based on normal capacity of production facilities. This statement is effective for Acme's fiscal year 2006. We do not expect the adoption of this standard to have a material effect on our financial position, results of operations or cash flows. (12)

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS-Continued Item 3. Quantitative and Qualitative Disclosure About Market Risk There are no material changes in market risks as disclosed in our annual Report on Form 10-K for the year ended December 31, 2004. Item 4. Controls and Procedures (a) Evaluation of Internal Controls and Procedures Our Chief Executive Officer and Chief Financial Officer have reviewed and evaluated the effectiveness of our disclosure controls and procedures, which included inquiries made to certain other of our employees. Based on their evaluation, our Chief Executive Officer and Chief Financial Officer have each concluded that, as of June 30, 2005, our disclosure controls and procedures were effective and sufficient to ensure that we record, process, summarize and report information required to be disclosed by us in our periodic reports filed under the Securities and Exchange Commission's rules and forms. (b) Changes in Internal Control over Financial Reporting During the quarter ended June 30, 2005, there were no changes in our internal control over financial reporting that materially affected, or was reasonably likely to materially affect, this control. (13)

PART II. OTHER INFORMATION Item 1 -- Legal Proceedings The Company is involved from time to time in disputes and other litigation in the ordinary course of business, including certain environmental and other matters. The Company presently believes that none of these matters, individually or in the aggregate, would be likely to have a material adverse impact on financial position, results of operations, or liquidity from these matters. Item 2 -- Unregistered Sales of Equity Securities and Use of Proceeds (c) On July 23, 2003, the Company announced a stock repurchase program of up to 150,000 shares. In April, 2005, all shares available under this program had been repurchased. On March 30, 2005, the Company announced a further stock repurchase program of up to 150,000 shares.

                          AND REAFFIRMATION OF GUARANTY


Acme United Corporation
1931 Black Rock Turnpike
Fairfield, Connecticut 06432
(Hereinafter referred to as "Borrower")

Acme United Limited
351 Foster Street
Mount Forest, Ontario, Canada, NOG 2LO
(Individually and collectively "Guarantor")

Wachovia Bank, National Association
300 Main Street
Stamford, Connecticut 06901
(Hereinafter referred to as "Bank")

THIS AGREEMENT is entered into as of September 30, 2004 by and between Bank,
Borrower and Guarantor.

                                    RECITALS

Bank is the holder of a certain Revolving Promissory Note in the original
principal amount of up to $10,000,000.00 (the "Note"), which is dated August 2,
2002, and which evidences a certain revolving loan from Bank to Borrower (the
"Loan");

The Loan is made pursuant to the terms of a certain Revolving Credit And
Security Agreement dated August 2, 2002 (the "Loan Agreement", and collectively
with the Note and all of the other documents which evidence or secure the Loan,
the "Loan Documents");

Borrower has requested a modification of the interest rate payable under the
Note, an extension of the maturity date of the Note, and certain other changes
to the Loan Documents and Bank has agreed to such modifications;

Pursuant to its Unconditional Guaranty dated August 2, 2002 (the "Guaranty"),
Guarantor unconditionally agreed to the full payment and performance of all
Guaranteed Obligations, as defined in the Guaranty;

In consideration of Bank's agreement to such modifications and the other
agreements contained herein, the parties agree as follows:


                                    AGREEMENT

ACKNOWLEDGMENT OF BALANCE. Borrower acknowledges that the most recent Commercial
Loan Invoice sent to Borrower with respect to the Indebtedness, as that term is
defined in the Loan Agreement, is correct.

MODIFICATIONS. 1. The Note is hereby modified as follows: a. The first sentence of the paragraph entitled "LIBOR Market Index Rate" is hereby deleted in its entirety and the following is substituted therefor: "LIBOR Market Index plus 1.50% per annum, as LIBOR Market Index may change from day to day (`LIBOR Market Index-Based Rate')." Any other reference in the Note or in any other Loan Documents to the LIBOR Market Index-Based Rate shall be deemed to refer to such rate of interest as modified hereby. b. The paragraph in the Note entitled "Revolving Credit Advances" is hereby deleted in its entirety and the following is substituted therefor: REVOLVING CREDIT ADVANCES. This is a revolving credit note. Borrower may borrow, repay and reborrow, and Bank may advance and readvance under this Note respectively from time to time (each an "Advance" and together the "Advances"), so long as the total indebtedness and all other Advances under the Loan Agreement outstanding at any one time does not exceed the principal amount stated on the face of this Note. Bank's obligation to advance or readvance under this Note shall terminate if an Event of Default exists. c. The maturity date of the Note of July 31, 2005, set forth in the paragraph entitled "Repayment Terms", is hereby amended to be June 30, 2007. Any other reference in the Note or in any other Loan Documents to the maturity date of the Note shall be deemed to refer to June 30, 2007. 2. The Loan Agreement is hereby modified as follows: a. The definitions of "Borrowing Base" and "Borrowing Base Certificate" set forth in the Loan Agreement are hereby deleted in their entirety. In furtherance of the foregoing: (i) Any other reference in the Loan Agreement or in any other Loan Documents to the Borrowing Base, or to the requirement that Borrower submit a Borrowing Base Certificate, is hereby deleted. (ii) Any use of the phrase "...will not exceed the lesser of (i) the Maximum Loan Amount and (ii) the Borrowing Base" in the Loan Agreement or in any other Loan Documents is hereby modified as follows: "...will not exceed the Maximum Loan Amount". (iii) Section 5.6(a) of the Loan Agreement, entitled "Periodic Borrowing Base Information" is hereby deleted in its entirety and the following is substituted therefor: "Summary Reports. Within twenty (20) days of the end of each month (or more frequently if required by Bank), a summary accounts receivable report and a summary inventory report, setting forth such information as Bank may require. Notwithstanding the foregoing, Bank reserves the right, under certain circumstances, to request and receive a monthly borrowing base certificate, detailed accounts receivable report and detailed inventory report, each setting forth such additional information as Bank may require, and to reinstate the requirement that Advances be made pursuant to a borrowing base formula. These circumstances are a material adverse change in the financial condition of the Borrower, a default by the Borrower of one or more loan covenants, or should the Bank deem itself under secured." b. The first sentence of Section 5.1 of the Loan Agreement, entitled "Use of Loan Proceeds" is hereby deleted in its entirety and the following is substituted therefor: "Shall use the proceeds of the Loan only for general corporate purposes, including working capital needs of the Borrower and its Subsidiaries (including repayment of such Subsidiaries debts), and for stock repurchases and dividend payments by the Borrower." (2)

c. The requirement that Bank be permitted to conduct field examinations of Borrower's properties set forth in Sections 5.5 and 10.3(iv) of the Loan Agreement, is hereby deleted, provided however that Bank reserves all rights set forth in the Loan Agreement and any other Loan Document to review Borrower's books and records at Bank's sole discretion. d. The dollar amount of $6,300,000.00 set forth in the first sentence of Section 7.2 of the Loan Agreement, entitled "Tangible Net Worth" is hereby modified to be $9,000,000.00. e. The ratio of 2.00 to 1.00 set forth in the first sentence of Section 7.3 of the Loan Agreement, entitled "Total Liabilities to Tangible Net Worth Ratio" is hereby modified to be 1.75 to 1.00. f. The definition of "Termination Date" set forth in the Loan Agreement is hereby deleted in its entirety, and the following is substituted therefor: "'Termination Date' means June 30, 2007. 3. Except as modified herein, all other terms, covenants and conditions set forth in any Loan Document shall remain unmodified and in full force and effect. ACKNOWLEDGMENTS AND REPRESENTATIONS. Borrower and Guarantor acknowledge and represent that the Note, the Loan Agreement, the Guaranty and all other Loan Documents, as amended hereby, are in full force and effect without any defense, counterclaim, right or claim of set-off; that, after giving effect to this Agreement, no default or event that with the passage of time or giving of notice would constitute a default under the Loan Documents has occurred; that all representations and warranties contained in the Loan Documents are true and correct as of this date; that all necessary action to authorize the execution and delivery of this Agreement has been taken; and that this Agreement is a modification of an existing obligation and is not a novation. COLLATERAL. Borrower and Guarantor acknowledge and confirm that there have been no changes in the ownership of the collateral pledged to secure the Loan (the "Collateral") since the Collateral was originally pledged; that the Bank has existing, valid first priority security interests and liens in the Collateral; and that such security interests and liens shall secure Borrower's and Guarantor's obligations to Bank, including without limitation the Note as amended hereby, and all future modifications, extensions, renewals and/or replacements of the Loan Documents. REAFFIRMATION OF GUARANTY. Guarantor hereby consents to the modifications contained herein and hereby ratifies and confirms: (a) that it unconditionally guarantees to Bank the payment and performance from and by Borrower of the Guaranteed Obligations, as defined in the Guaranty, upon the terms and conditions set forth in the Guaranty and (b) such Guaranteed Obligations include, without limitation, the Note and Loan Agreement as modified hereby. Guarantor acknowledges that its reaffirmation and ratification of the Guaranty is a material inducement for Bank to enter into this Agreement and that Bank would not do so without said reaffirmation and ratification. This Agreement and the Guaranty are Guarantor's valid and binding obligation enforceable against it in accordance with their terms. (3)
