              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 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 financial position, results of operations or
liquidity.


Note 3 -- Pension

Components of net periodic pension cost are as follows for the periods set forth
below:

had borrowings of $10,422,845 and $10,187,245, respectively, under the revolving

Note 5-- 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 include (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.

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. Based on our evaluation, there is no
effect to the Company's financial statements from the adoption of FIN 48. Our
evaluation 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 March 31, 2007. The Internal Revenue Service (IRS) is

                     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 such factors is set forth
in Item 1A "Risk Factors" of Part 1 of the Company's 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 the
Company's Annual Report on Form 10-K for the fiscal year ended December 31,
2006, except as follows:

Accounting for Stock-Based Compensation. In the first quarter of 2006, the
Company began accounting for stock-based compensation in accordance with the
fair value recognition provisions of Statement of Financial Accounting Standards
No. 123R "Share Based Payment" (SFAS 123R"). The Company uses the Black-Scholes
option - pricing model, which requires the input of subjective assumptions.
These assumptions include estimating the length of time employees will retain
their vested stock options before exercising them ("expected term"), the
estimated volatility of the Company's common stock price over the expected term
and the number of options that will ultimately not complete their vesting
requirements ("forfeitures"). Changes in the subjective assumptions can
materially affect the estimate of fair value stock-based compensation and
consequently, the related amount recognized on the consolidated statements of
operations. Refer to Note 7 "Stock Based Compensation" for a more detailed
discussion of the effects of SFAS 123R on our results of operations and
financial condition.

Results of Operations

Net Sales

Consolidated net sales for the quarter ended March 31, 2007 were $12,241,000,
compared with $12,257,000 for the same period in 2006. Net sales for the first
quarter in the U.S. operating segment decreased 4% over net sales for the same
period in 2006. Sales in the first quarter of 2006 included over $1 million of
initial new product shipments to three major retail chains. Since these products
are now regular items for these retailers, the first quarter of 2007's sales
represented only restocking shipments. Sales in Europe and Canada increased by
21% and 5% (in constant currency), respectively. Sales in Europe were positively
impacted by new sales to a large pan-European superstore and an expanded product
line with a major European retailer.

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 season.

Gross Profit

The gross profit for the first quarter of 2007 was $5,334,000 (44% of net sales)
compared to $5,552,000 (45% of net sales) for the first quarter of 2006. The
margin in 2007 declined due to a higher proportion of European sales, which
yield lower margins as compared to margins in the U.S. segment.


Selling, General and Administrative Expenses

Selling, general and administrative ("SG&A") expenses for the first quarter of
2007 were $4,158,000 (34% of net sales) compared with $4,259,000 (35% of net
sales) for the same period of 2006, a decrease of $101,000.


Operating Income

Operating income was $1,176,000 in the first quarter of 2007 compared with
$1,293,000 in the first quarter of 2006, representing a decrease of $116,000 or
9%. Operating income for the United States segment decreased by $106,000 or 8%,
primarily as a result of the decline in sales from the same period in 2006.
Operating income in Canada decreased by $12,000 or 17% primarily as a result of
a high proportion of sales to customers with lower margins. The European
operating loss remained relatively constant as compared to the same period in
2006.


Interest Expense

Interest expense for the first quarter of 2007 was $154,000, compared with
$125,000 for the same quarter of 2006, a $29,000 increase. The increase in
interest expense was primarily the result of higher borrowings under the
Company's bank revolving credit facility.


Other (Income) Expense, Net

Net other income was $27,000 in the first quarter of 2007 compared to net other
income of $76,000 in the first quarter of 2006. The change from 2006 is
primarily due to lower gains from foreign currency transactions in the first
quarter of 2007.


Income Taxes

The effective tax rate in the first quarter of 2007 was 38% compared to 39% in
the first quarter of 2006.

Financial Condition

Liquidity and Capital Resources

The Company's working capital, current ratio and long-term debt to equity ratio
follow:

                                           March 31, 2007    December 31, 2006
                                        -----------------    -----------------
Working capital                            $  26,256,910        $  25,460,578
Current ratio                                       6.51                 5.22
Long term debt to equity ratio                      56.3%                56.3%


During the first three months of 2007, total debt increased by $236,000 compared
to total debt at December 31, 2006, principally as a result of the buildup of
inventory in anticipation of future business and the repurchase of common stock
under a previously announced repurchase program, partially offset by earnings.

On March 6, 2006, 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 $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 will be used for working capital,
general operating expenses and certain other purposes. As of March 31, 2007,
$10,423,000 was outstanding and $4,577,000 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.
