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, 2006 for such disclosures. The condensed consolidated balance sheet as of December 31, 2006 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 2006 Annual Report on Form 10-K. 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 the financial position, results of operations or liquidity of the Company. Note 3 -- Pension Components of net periodic pension cost are as follows: Three Months Ended Nine Months Ended September 30, September 30, ------------------------------ -------------------------------- 2007 2006 2007 2006 -------------- -------------- --------------- --------------- Components of net periodic benefit cost: Interest cost $ 47,500 $ 46,974 $ 142,500 $ 140,922 Service cost 7,500 7,500 22,500 22,500 Expected return on plan assets (57,500) (57,149) (172,500) (171,447) Amortization of prior service costs 2,250 2,194 6,750 6,582 Amortization of actuarial gain 22,000 23,204 66,000 69,612 ----------------------------------------------------------------- $ 21,750 $ 22,723 $ 65,250 $ 68,169 ================================================================= Note 4 -- Long Term Debt and Shareholders Equity The Company's revolving loan agreement, as amended, provides for borrowings up to $15 million with all principal amounts outstanding there under required to be repaid in a single amount on June 30, 2009. In addition, the Company's revolving loan agreement requires monthly interest payments. At September 30, 2007 and December 31, 2006, the Company had outstanding borrowings of $12,269,565 and $10,187,245, respectively under the revolving loan agreement. Based on the scheduled payment date for the principal, the Company has classified all borrowings under the revolving loan agreement at September 30, 2007 as long-term liabilities.

Note 5 -- Segment Information The Company reports financial information based on the organizational 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 "business" or "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.

Note 6 - Stock Based Compensation The Company recognizes share-based compensation in accordance with the provisions of Statement of Financial Accounting Standards No. 123R, "Share-Based Payment" ("SFAS 123R"). Share-based compensation expense was $74,000 and $48,000 for the quarters ended September 30, 2007 and September 30, 2006, respectively. Share-based compensation expense was $257,000 and $222,000 for the nine months ended September 30, 2007 and September 30, 2006, respectively. The Company did not issue options during the three months ended September 30, 2007. During the nine months ended September 30, 2007, the Company issued 98,250 options with a weighted average fair value of $4.96. During the three and nine months ended September 30, 2006, the Company issued 63,000 and 113,500 options with a fair values of $4.35 and $4.81, respectively. The assumptions used to value option grants for the three and nine months ended September 30, 2007 and September 30, 2006 are as follows: Three months ended Nine months ended September 30, September 30, ------------------------------ ------------------------------ 2007 2006 2007 2006 -------------- -------------- -------------- -------------- Expected life in years 5 5 5 4-5 Interest rate 4.51 - 5.18% 4.91% 4.51 - 5.18% 4.32 - 4.91% Volatility 0.32 0.33 .32 .33 - .34 Dividend yield 1.1% 0.80% 1.1% 0.80 - 0.90% As of September 30, 2007, there was $591,486 of unrecognized compensation cost adjusted for estimated forfeitures, related to non-vested share -based payments granted to the Company's employees. The remaining unamortized expense is expected to be recognized over a weighted average period of approximately 3 years. Note 7 - Comprehensive Income Comprehensive income for the three and nine months ended September 30, 2007 and September 30, 2006 consisted of the following: Three Months Ended Nine Months Ended September 30, September 30, ------------------------------ ------------------------------ 2007 2006 2007 2006 -------------- -------------- -------------- -------------- (in thousands) Net Income $ 1,305 $ 1,225 $ 3,476 $ 3,490 Other comprehensive income / (loss) - Foreign currency translation 660 (31) 1,192 192 -------------- -------------- -------------- -------------- Comprehensive income $ 1,965 $ 1,194 $ 4,668 $ 3,682 ============== ============== ============== ============== Note 8 - Income Taxes The Company adopted the provisions of Financial Accounting Standards Board ("FASB") Interpretation No. 48, "Accounting for Uncertainty in Income Taxes-an interpretation of FASB Statement No. 109" ("FIN 48"), on January 1, 2007. FIN 48 clarifies the accounting for uncertainty in income taxes recognized in an enterprise's financial statements in accordance with FASB Statement 109, "Accounting for Income Taxes", and prescribes a recognition threshold and measurement process for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. FIN 48 also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. The Company files income tax returns in the U.S. federal jurisdiction, and various state and foreign jurisdictions. There was no effect on the Company's financial statements as a result of the adoption of FIN 48. The Company's evaluation of FIN 48 was performed for the tax years ended December 31, 2003, 2004, 2005 and 2006, the tax years which remain subject to examination by major tax jurisdictions as of September 30, 2007. The Internal Revenue Service (IRS) completed its examination of the Company's U.S. federal income tax return for 2004 with no changes. (9)

In accordance with the Company's accounting policies, any interest and penalties related to uncertain tax positions are recognized in income tax expense. Note 9 - Business Combinations On September 18, 2007, the Company purchased certain assets of the Camillus Cutlery Company ("Camillus Cutlery") for $246,000, consisting primarily of trademarks, brand names and patents. Camillus Cutlery, founded in 1873, is one of the oldest knife companies in the U.S. Camillus Cutlery's products include many types of folding knives, as well as those for hunting and fishing. On September 25, 2007, the Company purchased certain assets of Tiger Sharp Technologies Inc. ("Tiger Sharp") for $355,000, consisting primarily of trademarks, brand names and patents. The purchase agreement also included a royalty arrangement whereby Acme United will, for a period of three years, pay Tiger Sharp a 5% royalty on the company's sales of Tiger Sharp patented products and a 1% royalty on the Company's sales of a certain product which is currently in development. Tiger Sharp was founded in 2002 in Dallas, Texas to commercialize its unique replaceable blade technology. The Company has pioneered many extremely sharp replaceable blade folding knives. Proforma operating information for the periods prior to these acquisitions is not provided because of the immateriality of the transactions on a proforma basis. (10)

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. A more detailed discussion of risk factors is set forth in Item 1A, "Risk Factors", included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2006. 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, 2006. Results of Operations Net Sales Consolidated net sales for the three months ended September 30, 2007 were $17,081,000 compared with $15,532,000 in the same period in 2006, a 10% increase (8% at constant currency). Consolidated net sales for the nine months ended September 30, 2007 were $48,321,000, compared with $44,774,000 for the same period in 2006, an 8% increase (7% at constant currency). Net sales for the first nine months ended September 30, 2007 in the U.S. operating segment increased 6% primarily as the result of sales of new products, including the new iPoint electric pencil sharpener and market share gains. Sales for the nine month period in Canada increased by 9% (6% in local currency) due to sales of the new iPoint electric pencil sharpeners and other new office products. Sales for the nine month period in Europe increased by 20% (12% in local currency) mainly due to higher sales of manicure items and expansion in the office trade channel. 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 September 30, 2007 was $7,381,000 (43.2% of net sales) compared to $6,624,000 (42.6% of net sales) for the same period in 2006. The gross margin increase for the third quarter was principally due to improved margins in Europe and the success of new products. Gross profit for the nine months ended September 30, 2007 was $20,694,000 (42.8% of net sales) compared to $19,604,000 (43.8% of net sales) in the same period in 2006. The lower margin percentage in the first nine months of 2007, as compared to the same period in 2006, was primarily the result of greater sales of lower margin products, increased raw material costs and the appreciation of the Chinese currency. (11)

Selling, General and Administrative Expenses Selling, general and administrative ("SG&A") expenses for the three months ended September 30, 2007 were $5,229,000 (30.6% of net sales) compared with $4,506,000 (29.0% of net sales) for the same period of 2006, an increase of $723,000. SG&A expenses for the nine months ended September 30, 2007 were $14,822,000 (30.7% of net sales) compared with $13,760,000 (30.7% of net sales) in the comparable period of 2006, an increase of $1,062,000. The increases in SG&A expenses for the three and nine months ended September 30, 2007, compared to the same periods in 2006, were primarily the result of the addition of sales, marketing and quality control personnel and incrementally higher sales commissions and freight costs associated with higher sales. Operating Income Operating income for the three months ended September 30, 2007 was $2,152,000, compared with $2,118,000 in the same period of 2006, an increase of $34,000. Operating income in Canada decreased by $90,000 in the third quarter 2007, compared to the third quarter 2006. Canada's decrease in operating income was principally due to earlier shipments of back to school items this year for which the related revenues were recognized in earlier periods. Operating profit in Canada in the second quarter of 2007 was $80,000 higher than in the comparable period last year. The European operating loss for the three months ended September 30, 2007 improved from $145,000 to $63,000. Total company operating income for the nine months ended September 30, 2007 was $5,872,000, as compared to $5,844,000 in the same period of 2006. The European operating loss for the nine months ended September 30, 2007 improved from $536,000 to $397,000. The decease in the European operating loss was mainly due to sales growth and improved gross margins as a result lower packaging and airfreight expenses. Interest Expense Interest expense for the three months ended September 30, 2007 was $208,000, compared with $207,000 for the same period of 2006. Interest expense for the nine months ended September 30, 2007 was $519,000 as compared to $462,000 for the same period in 2006, a $57,000 increase. The increase in interest expense during the first nine months of 2007 over the comparable period in 2006 was primarily the result of higher borrowings under the Company's bank revolving credit facility used to finance the company's increase in sales during the same period. Other Income, Net Net other income was $91,000 in the three months ended September 30, 2007, compared to $35,000 in the same period of 2006, an increase of $56,000. Net other income was $77,000 in the first nine months of 2007 compared to $149,000 in the first nine months of 2006, a decrease of $72,000. The decrease in other income during the first nine months of 2007 was primarily due to lower gains from foreign currency transactions. Income Taxes The effective tax rate in the first nine months of 2007 was 36% compared to 37% in the first nine months of 2006. The 1% decrease in the Company's effective tax rate was primarily due to the Company's 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.

Financial Condition Liquidity and Capital Resources The Company's working capital, current ratio and long-term debt to equity ratio follow: September 30, 2007 December 31, 2006 ------------------ ----------------- Working capital $ 31,170,370 $ 25,460,078 Current ratio 5.14 5.22 Long term debt to equity ratio 55.2% 56.3% On March 6, 2006, the Company modified its Revolving Loan Agreement (the "Modified Loan Agreement") with Wachovia Bank. The Modified Loan Agreement amended certain provisions of the original Revolving Loan Agreement. The amendments include an increase in the maximum borrowing amount from $10 million to $15 million; an extension of the maturity date of the loan from June 30, 2007 to June 30, 2009; a decrease in the interest rate to LIBOR plus 1% (from LIBOR plus 1.5%), as well as modifications to certain covenant restrictions. Funds borrowed under the Modified Loan Agreement are used for working capital, general operating expenses and certain other purposes. During the first nine months of 2007, total debt outstanding under the Company's Modified Loan Agreement increased by $2,082,320 compared to December 31, 2006, principally due to an increase in borrowings for inventory needed for anticipated sales growth, and accounts receivables resulting from the back to school season, partially offset by earnings. The increase in the company's working capital of $5,709,292, from December 31, 2006 to September 30, 2007, was primarily due to increase in inventory and accounts receivables financed by long-term debt. Such increases in inventory and accounts receivables were principally due to anticipated sales growth and increased sales from the back to school season, respectively. Additionally, the Company spent a total of approximately $601,000 on two acquisitions (see Note 9 to the Company's condensed consolidated financial statements in Part I, Item 1 of this Form 10-Q) and repurchased company stock for $486,000 during the first nine months of 2007 in accordance with the Company's previously announced stock repurchase program. As of September 30, 2007, $12,270,000 was outstanding and $2,730,000 was available for borrowing under the Modified Loan Agreement. 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.
