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 of Acme United Corporation (the "Company"). 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, 2007 for such disclosures. The condensed consolidated balance sheet as of December 31, 2007 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. The information included in this Quarterly Report on Form 10-Q should be read in conjunction with the Management's Discussion and Analysis of Financial Condition and Results of Operations and financial statements and notes thereto, included in the Company's 2007 Annual Report on Form 10-K. Reclassifications - Certain prior year amounts have been reclassified to conform to the current year presentation. Note 2 -- Contingencies The Company is involved from time to time in disputes and other litigation in the ordinary course of business and may encounter other contingencies, which may include 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 its financial position, results of operations or liquidity. Note 3 -- Pension Components of net periodic pension cost are as follows: Three Months Ended June 30, Six Months Ended June 30, ------------------------------ ------------------------------- 2008 2007 2008 2007 -------------- -------------- -------------- -------------- Components of net periodic benefit cost: Interest cost $ 45,000 $ 45,948 $ 90,000 $ 91,896 Service cost 7,500 6,250 15,000 12,500 Expected return on plan assets (56,250) (62,048) (112,500) (124,096) Amortization of prior service costs 2,250 2,138 4,500 4,276 Amortization of actuarial gain 18,750 24,408 37,500 48,816 ----------------------------------------------------------------- $ 17,250 $ 16,696 $ 34,500 $ 33,392 ================================================================= Note 4 -- Long Term Debt On June 23, 2008, the Company modified its revolving loan agreement (the "Modified Loan Agreement") with Wachovia Bank. The amendments include an increase in the maximum borrowing amount from $15 million to $20 million; an extension of the maturity date of the loan from June 30, 2009 to June 30, 2010; a decrease in the interest rate to LIBOR plus 7/8% (from LIBOR plus 1.0%) as well as the modification of certain covenant restrictions. Funds borrowed under the Modified Loan Agreement are primarily used for working capital, general operating expenses and certain other purposes. At June 30, 2008 and December 31, 2007, the Company had outstanding borrowings under the Modified Loan Agreement of $14,949,000 and $10,098,000, respectively. Based on the scheduled maturity date, the Company has classified the borrowings at June 30, 2008 as long-term liabilities. (7)

Note 5 -- Shareholder's Equity During the first six months of 2008, the Company issued 25,750 shares of common stock upon the exercise of outstanding stock options and received proceeds of $132,818. During the same period, the Company also repurchased 57,200 shares of common stock for treasury. These shares were purchased at fair market value, with a total cost to the Company of $786,866. Note 6 -- Segment Information The Company reports financial information based on the organization structure used by management for making operating and investment decisions and for assessing performance. The Company's reportable business segments consist of (1) United States; (2) Canada and (3) Europe. The activities of the Company's Asian operating segment are closely linked to those of the U.S. operating segment; accordingly, management reviews the financial results of both segments on a consolidated basis, and the results of the Asian operating segment have been aggregated with the results of the United States operating segment to form one reportable segment called the "United States operating segment". The determination of reportable segments is based on the guidance set forth in SFAS No. 131, "Disclosures about Segments of an Enterprise and Related Information". Each reportable segment derives its revenue from the sales of cutting devices, measuring instruments and safety products for school, office, home and industrial use. The chief operating decision maker evaluates the performance of each operating segment based on segment revenues and operating income. Segment amounts are presented after converting to U.S. dollars and consolidating eliminations.

Share-based compensation expense was $94,000 and $131,000 for the quarters ended June 30, 2008 and June 30, 2007, respectively. Share-based compensation expense was $166,000 and $184,000 for the six months ended June 30, 2008 and June 30, 2007, respectively. During the three and six months ended June 30, 2008, the Company issued 12,250 options with a weighted average fair value of $3.86. During the three and six months ended June 30, 2007, the Company issued 97,750 options with a weighted average fair value of $4.96. The assumptions used to value option grants for the three and six months ended June 30, 2008 and June 30, 2007 are as follows: Three months ended Six months ended June 30, June 30, ---------------------------- ------------------------------ 2008 2007 2008 2007 ---------------------------- ------------------------------ Expected life in years 5 5 5 5 Interest rate 2.95% 4.51 - 5.18% 2.95% 4.51 - 5.18% Volatility 0.31 0.32 .31 .32 Dividend yield 1.2% 1.1% 1.2% 1.1% As of June 30, 2008, there was a total of $398,078 of unrecognized compensation cost related to non-vested share -based payments granted to the Company's employees.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS Item 2. - Management's Discussion and Analysis of Financial Condition and 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. Critical Accounting Policies There have been no material changes to our critical accounting policies and estimates from the information provided in Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations, included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2007. Results of Operations Net Sales Consolidated net sales for the three months ended June 30, 2008 were $22,708,000 compared with $18,999,000 in the same period in 2007, a 20% increase (17% at constant currency). Consolidated net sales for the six months ended June 30, 2008 were $36,977,000, compared with $31,240,000 for the same period in 2007, an 18% increase (15% at constant currency). Net sales for the three and six months ended June 30, 2008 in the U.S. segment increased 23% and 21%, respectively, primarily as a result of market acceptance of new anti-microbial school scissors, rulers, and math kits and iPoint pencil sharpeners. Net sales in Canada in the three and six months ended June 30, 2008 increased by 3% and 5% in U.S. dollars but declined 5% and 6% in local currency, primarily due to soft demand in the overall office products market. European net sales for the three and six months ended June 30, 2008 increased 18% in U.S. dollars and 3% in local currency. 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 market. Gross Profit Gross profit for the three months ended June 30, 2008 was $8,918,000 (39.3% of net sales) compared to $7,979,000 (42.0% of net sales) for the same period in 2007. Gross profit for the six months ended June 30, 2008 was $14,904,000 (40.3% of net sales) compared to $13,313,000 (42.6% of net sales) in the same period in 2007. The gross margin declines for the three and six months ended June 30, 2008 were primarily due to increased costs of material, labor and energy, as well as the appreciation of the Chinese currency against the U.S. dollar. Also, during the second quarter of 2008 the company gained additional market share in the highly competitive back to school segment which reduced gross margins. (10)

Selling, General and Administrative Expenses Selling, general and administrative ("SG&A") expenses for the three months ended June 30, 2008 were $6,121,000 (27.0% of net sales) compared with $5,435,000 (28.6% of net sales) for the same period of 2007, an increase of $686,000. SG&A expenses for the six months ended June 30, 2008 were $11,039,000 (29.9% of net sales) compared with $9,593,000 (30.7% of net sales) in the comparable period of 2007, an increase of $1,446,000. SG&A expenses increased for the three and six months ended June 30, 2008 primarily as a result of the addition of sales, marketing and quality control personnel as well as incrementally higher freight costs and sales commissions associated with higher sales. Operating Income Operating income for the three months ended June 30, 2008 was $2,797,000 compared with $2,544,000 in the same period of 2007. Operating income for the six months ended June 30, 2008 was $3,865,000 compared to $3,720,000 in the same period of 2007. Interest Expense Interest expense for the three months ended June 30, 2008 was $90,000, compared with $156,000 for the same period of 2007, a $66,000 decrease. Interest expense for the six months ended June 30, 2008 was $187,000 as compared to $310,000 for the same period in 2007, a $123,000 decrease. The decrease in interest expense for both the three and six months ended June 30, 2008 was primarily the result of lower interest rates under the Company's revolving credit facility, partially offset by a higher average outstanding debt balance. Other Expense (Income), Net Net other expense was $24,000 in the three months ended June 30, 2008 as compared to $41,000 in the same period of 2007. Net other income was $162,000 in the first six months of 2008 compared to net other expense of $14,000 in the first six months of 2007. The increase other expense (income), net for the six months ended June 30, 2008 was primarily due to gains from foreign currency transactions. Income Taxes The effective tax rate for the three months ended June 30, 2008 was 36% compared to 35% in the same period of 2007. The effective tax rate for the six months ended June 30, 2008 was 35% compared to 36% in the same period of 2007. (11)

Financial Condition Liquidity and Capital Resources The Company's working capital, current ratio and long-term debt to equity ratio follow: (000's omitted) June 30, 2008 December 31, 2007 ------------------------------------ Working capital $ 35,881 $ 29,326 Current ratio 4.19 4.44 Long term debt to equity ratio 60.6% 44.0% During the first six months of 2008, total debt outstanding under the Company's Modified Loan agreement, referred to below, increased by $4,851,000 compared to total debt at December 31, 2007, principally due to an increase in borrowings for inventory and accounts receivables for the back to school season as well as share repurchases, partially offset by earnings. As of June 30, 2008, $14,949,000 was outstanding and $5,051,000 was available for borrowing under the Modified Loan Agreement. On June 23, 2008, the Company modified its Revolving Loan Agreement (the "Modified Loan Agreement") with Wachovia Bank. The Modified Loan Agreement amends certain provisions of the original Revolving Loan Agreement. The amendments include an increase in the maximum borrowing amount from $15 million to $20 million; an extension of the maturity date of the loan from June 30, 2009 to June 30, 2010; and a decrease in the interest rate to LIBOR plus 7/8% (from LIBOR plus 1.0%). Funds borrowed under the Modified Loan Agreement are used for working capital, general operating expenses and certain other purposes. Cash expected to be generated from operating activities, together with funds available under the Modified Loan Agreement are expected, under current conditions, to be sufficient to finance the Company's planned operations over the next twelve months. Recently Issued Accounting Standards In September 2006, the FASB issued SFAS No. 157, "Fair Value Measurements" ("SFAS No. 157"). SFAS No. 157 defines fair value, establishes a framework for measuring fair value in GAAP and establishes a hierarchy that categorizes and prioritizes the sources to be used to estimate fair value. SFAS No. 157 also expands financial statement disclosures about fair value measurements. On February 12, 2008, the FASB issued FASB Staff Position (FSP) 157-2 which delays the effective date of SFAS No. 157 for one year, for all non-financial assets and non-financial liabilities, except those that are recognized or disclosed at fair value in the financial statements on a recurring basis (at least annually). SFAS No. 157 and FSP 157-2 are effective for financial statements issued for fiscal years beginning after November 15, 2007. We will elect a partial deferral of SFAS No. 157 under the provisions of FSP 157-2 related to the measurement of fair value used when evaluating long-lived assets for impairment and valuing asset retirement obligations. The impact of partially adopting SFAS No. 157 effective January 1, 2008 will not be material to our financial statements. In February 2007, the FASB issued SFAS No. 159, "The Fair Value Option for Financial Assets and Financial Liabilities," ("SFAS No. 159") which provides companies with an option to report selected financial assets and liabilities at fair value in an attempt to reduce both complexity in accounting for financial instruments and the volatility in earnings caused by measuring related assets and liabilities differently. This statement is effective as of the beginning of an entity's first fiscal year beginning after November 15, 2007. The Company chose not to adopt these fair value provisions. (12)

Item 3. Quantitative and Qualitative Disclosure About Market Risk There are no material changes in market risks as disclosed in the Company's annual Report on Form 10-K for the year ended December 31, 2007. 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, 2008, 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, 2008, there were no changes in our internal control over financial reporting that materially affected, or was reasonably likely to materially affect, this control.
