              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.


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:

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 operations are closely linked to those of the U.S. operations;
accordingly, management reviews the financial results of both segments on a
consolidated basis, and the results of the Asian operations have been aggregated
with the results of the United States operations 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 Statement of
Financial Accounting Standards No. 131, "Disclosures about Segments of an
Enterprise and Related Information" ("SFAS 131"),. 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.

                     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, 2007. 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 the Company's 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, 2007.


Results of Operations

Net Sales

     Consolidated net sales for the three months ended March 31, 2008 were
$14,269,000, compared with $12,241,000 in the same period in 2007, a 17%
increase (13% at constant currency). Net sales in the U.S. operating segment
increased 17% for the three months ended March 31, 2008, principally due to
higher sales of pencil sharpeners, over-the-counter medications and paper
trimmers. Net sales in Canada decreased by 7% in local currency due to soft
demand in the overall office products market. Net sales in Europe decreased by
4% 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 March 31, 2008 was $5,986,000
(41.9% of net sales), compared to $5,334,000 (43.6% of net sales) for the same
period in 2007, a decrease of 1.7%. The gross margin decrease for the first
quarter was principally due to a higher proportion of sales of medications in
the U.S. segment, which carry a lower gross margin than the Company's other
product lines. This decrease was partially offset by gross margin percentage
increases in both the Canadian and European operating segments. These increases
were principally related to a favorable customer/product mix.

                                      (10)


Selling, General and Administrative Expenses

     Selling, general and administrative ("SG&A") expenses for the three months
ended March 31, 2008 were $4,918,000 (34.5% of net sales), compared with
$4,158,000 (34.0% of net sales) for the same period of 2007, an increase of
$760,000. The increase in SG&A expenses for the three months ended March 31,
2008, compared to the same period in 2007, was primarily the result of the
addition of sales, marketing and quality control personnel as well as
incrementally higher sales commissions and freight costs associated with higher
sales.


Operating Income

     Operating income for the three months ended March 31, 2008 was $1,068,000,
compared with $1,176,000 in the same period of 2007, a decrease of $108,000.
Operating income in the U.S. segment decreased by $213,000 or 16% in the first
quarter of 2008, compared to the same period of 2007 principally due to product
mix and increased SG&A expenses. Operating income in Canada and Europe increased
by approximately $53,000 and $50,000, respectively, in the first quarter of 2008
compared to the same period in 2007.


Interest Expense, Net

     Interest expense for the three months ended March 31, 2008 was $96,000,
compared with $154,000 for the same period of 2007, a decrease of $58,000. The
decrease in interest expense during the first three months of 2008 over the
comparable period in 2007 was primarily the result of lower interest rates on
the Company's debt outstanding under its revolving loan agreement.


Other Income, Net

     Net other income was $186,000 in the first quarter of 2008, compared to net
other income of $27,000 in the first quarter of 2007, an increase of $159,000.
The change from 2007 is primarily due to gains from foreign currency
transactions.


Income Taxes

The effective tax rate in the first quarter of 2008 was 35%, compared to 38% in
the first quarter of 2007.

                                          -------------------------------------
Working capital                             $  31,785,762        $  29,377,846
Current ratio                                        5.66                 4.46
Long term debt to equity ratio                       55.4%                44.2%


During the first three months of 2008, total debt increased by $2,524,000,
compared to total debt at December 31, 2007 principally as a result of
additional borrowings under the revolving loan agreement related to the buildup
of inventory in anticipation of future business, and the repurchase of common
stock under a previously announced repurchase program, partially offset by cash
generated from operations.

Under the Company's revolving loan agreement with Wachovia, the maximum
borrowing amount is $15 million, the interest rate is LIBOR plus 1% and the
maturity date is June 30, 2009. Funds borrowed under the revolving loan
agreement will be used for working capital, general operating expenses and
certain other purposes. As of March 31, 2008, $12,670,000 was outstanding and
$2,330,000 was available for borrowing under the revolving loan agreement.

Cash expected to be generated from operating activities, together with funds
available under the revolving 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 nonfinancial assets and
nonfinancial 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.
