                                   (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, 2003 for such disclosures. The condensed
consolidated balance sheet as of December 31, 2003 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

In the June 30, 2004 10Q the Company reported that it was involved in a legal
action that was in its preliminary stages. During the third quarter 2004 this
proceeding was settled on terms satisfactory to management with no material
effect on the Company.

The Company is involved from time to time in disputes and other litigations 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:

The Company previously disclosed in its financial statements for
the year ended December 31, 2003 that it expected to contribute $29,000 to its
pension plan. As of September 30, 2004, no contributions have been made. The
Company has recalculated the expected contribution and determined that
contributions to its pension plan in 2004 are not required. Therefore, the
Company does not intend to contribute to the pension plan in 2004.

Note 4 -- Accounting for Stock-Based Compensation

At September 30, 2004, the Company has one stock-based employee compensation
plan. The Company has elected to adopt the disclosure only 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. See Note 7 for shares exercised in
2004.

Note 5 -- Litigation Settlement

As a result of significant developments in the first quarter of 2003 the
Company's German subsidiary settled litigation for $175,000. This amount
exceeded previous accruals by $153,000 and was charged to other expense.

Note 6 -- Income Taxes

In 2004 and 2003, consolidated income before income taxes includes losses of
foreign subsidiaries with no income tax benefit, resulting in an effective
consolidated income tax rate greater than the United States statutory rate.

Note 7 -- Capital Structure

During the first nine months of 2004, the Company issued 187,200 shares of
common stock with proceeds of $662,892 upon the exercise of outstanding stock
options. The company also repurchased 46,830 shares of common stock for
treasury. The shares were purchased at fair market value, with a total cost to
the Company of $235,598. During the first quarter, an additional $31,225 of
compensation expense was charged to operating results as a result of the
Company's repurchase of 16,000 shares within six months of exercise of certain
options by a terminated employee.

Note 8 -- Business Combination

On May 28, 2004, the Company purchased Clauss Cutlery, a division of Alco
Industries, Inc.. The scissor and cutting business at Clauss is expected to
generate approximately $2.0 million in annual net revenues. The purchase price
was the aggregate value of inventory, trademarks and brand names totaling
$446,754. Included in the purchase price is a stand-by letter of credit the
Company issued in the amount of $230,000 for a trademark from Alco Industries,
Inc. that was renewed by the U.S. Patent and Trademark Office on July 13, 2004.
The letter of credit was set-up to expire on May 28, 2005, if the trademark was
not renewed. Since the trademark was renewed prior to the expiration date, Alco
Industries, Inc. enforced the letter of credit and drew down the funds. Included
in the accompanying Statement of Operations are the operations of the acquired
business since the date of acquisition. In accordance with Regulation S-X,
proforma information is not provided because of the immateriality of the
transaction.

Note 9 -- Impairment of Equipment

During the second quarter of 2004, the Company abandoned its ruler manufacturing
equipment. In accordance with FASB 144, Accounting for the Impairment or
Disposal of Long-Lived Assets, the Company recorded an impairment loss of
$84,820, or $0.02 a share, for the full amount of the assets at the time of
abandonment.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF

                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS

             For the Three and Nine Months Ended September 30, 2004


Item 2.  - Results of Operations

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 business specific to the back-to-school season.
Consolidated net sales for the quarter ended September 30, 2004 were $11,595,000
compared with $9,538,000 for 2003, a 22% increase. Net sales for the first nine
months of 2004 were $32,460,000 compared with $26,869,000 for 2003, a 21%
increase. Excluding the favorable effect of currency gains in Canada and Europe,
net sales for the first nine months increased 19%. The sales increase was mainly
driven by a 21% increase in the U.S. due to market share gains and new product
launches. The new business in Hong Kong generated $883,000 in the first nine
months of 2004.


Gross Profit

The gross profit for the third quarter of 2004 was $5,453,000 (47.0% of net
sales) compared to $3,171,000 (33.2% of net sales) for the third quarter of
2003. The gross profit in 2003 included approximately $200,000 of costs
associated with the closure of manufacturing in Germany. Gross margins for the
third quarter of 2003 without this effect were 35.3%. Gross profit for the first
nine months of 2004 was 45.3% of net sales compared to 37.1% in the same period
of 2003. The introduction of new products coupled with positive impacts from
product rationalization efforts in Europe were the main reasons for the improved
gross margins.


Selling, General and Administrative Expenses

Selling, general and administrative ("SG&A") expenses for the third quarter of
2004 were $3,739,000 (32% of net sales) compared with $2,648,000 (28% of net
sales) for the same period of 2003, an increase of $1,091,000. SG&A expenses
were 32% of net sales for the first nine months of 2004 versus 29% in the
comparable period of 2003. The majority of the increase in SG&A expenses in 2004
was selling related expenses, the new sourcing and quality control office in
Hong Kong and the addition of sales and marketing personnel in North America and
Europe.


Interest Expense

Interest expense for the first nine months of 2004 was $131,000, compared with
$190,000 for 2003, a $59,000 decrease. This is mainly attributable to the
decline in debt.


Other Expense

Net other expense was $126,000 in the first nine months of 2004 compared to
$55,000 in the first nine months of 2003.


Income Before Income Taxes

Income before income taxes was $1,616,000 in the third quarter of 2004 compared
with $565,000 in the third quarter of 2003, an increase of $1,051,000. Income
before income taxes was $4,146,000 for the first nine months of 2004 compared
with $1,874,000 in the first nine months of 2003, an improvement of $2,272,000.
Pretax income for North America and Asia increased by approximately $2.1
million. The European operations had a slightly higher loss (exclusive of one
time expenses of approximately $300,000) in the first nine months of 2004
compared to 2003. Increased investment in sales and marketing efforts resulted
in higher costs.

                                      (10)
<PAGE>

Income Taxes

The effective tax rate in the first nine months of 2004 was 40% compared to 46%
in 2003, which was effected by the one time charge for the closing of
manufacturing facilities in Germany. The improvement is principally due to the
lower losses in Europe, for which the benefit cannot be utilized to offset
earnings.

Net Income

Net income for the third quarter of 2004 was $1,017,000, or 26 cents per share
(diluted), compared to a net income of $302,000, or 8 cents per share (diluted)
for the same period of 2003. Net income for the first nine months of 2004 was
$2,484,000, or 66 cents per share (diluted), compared to a net income of
$995,000, or 28 cents per share (diluted) for the same period of 2003.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF

             FINANCIAL CONDITION AND RESULTS OF OPERATIONS-Continued

             For the Three and Nine Months Ended September 30, 2004

Financial Condition

Liquidity and Capital Resources

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

                                     September 30, 2004      December 31, 2003
                                     ------------------     ------------------

Working capital.....................      $13,101,000           $10,778,000
Current ratio.......................        2.56 to 1             2.68 to 1
Long-term debt to equity ratio......            17.7%                 27.0%


During the first nine months of 2004, total debt decreased by $1,479,000
compared to total debt at December 31, 2003 principally as a result of seasonal
collection terms which mature during the later half of the third quarter.


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 applies specific percentages to balances of
accounts receivable and inventory. The renewal modified several characteristics
of the original agreement, the most significant of which are reducing the
interest rate to LIBOR plus 1.50 percent, 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 September 30, 2004, $3,161,613 was outstanding and $6,838,387
was available for borrowing under this agreement. The estimated maturities of
all long-term debt follow: 2005 - $1,000,000, 2006 - $1,600,000, 2007 -
$708,174.

Cash expected to be generated from operating activities, 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.

There are no material changes in market risks since our most recent filing on
Form 10-K for the year ended December 31, 2003.


Item 4. Controls and Procedures

(a)  Evaluation of Internal Controls and Procedures

report information required to be disclosed by us in our periodic reports filed
under the Securities and Exchange Commission's rules and forms.

reasonably likely to materially affect, this control.

                           PART II. OTHER INFORMATION

Item 1 -- Legal Proceedings

In the June 30, 2004 10Q the Company reported that it was involved in a legal
action that was in its preliminary stages. During the third quarter 2004 this
proceeding was settled on terms satisfactory to management with no material
effect on the Company.

The Company is involved from time to time in disputes and other litigations 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.

                  SECTION 302 OF THE SARBANES-OXLEY ACT OF 2002

I, WALTER C. JOHNSEN, certify that:

     I have reviewed this Quarterly Report on Form 10-Q of Acme United
     Corporation;

     Based on my knowledge, this report does not contain any untrue statement of
     a material fact or omit to state a material fact necessary to make the
     statements made, in light of the circumstances under which such statements
     were made, not misleading with respect to the period covered by this
     report;

     Based on my knowledge, the financial statements, and other financial
     information included in this report, fairly present in all material
     respects the financial condition, results of operations and cash flows of
     the registrant as of, and for, the periods presented in this report;

     The registrant's other certifying officer(s) and I are responsible for
     establishing and maintaining disclosure controls and procedures (as defined
     in Exchange Act Rules 13a-15(e) and 15d-15(e)) for the registrant and have:

         (a) Designed such disclosure controls and procedures, or caused such
         disclosure controls and procedures to be designed under our
         supervision, to ensure that material information relating to the
         registrant, including its consolidated subsidiaries, is made known to
         us by others within those entities, particularly during the period in
         which this report is being prepared;

         (b) Evaluated the effectiveness of the registrant's disclosure controls
         and procedures and presented in this report our conclusions about the
         effectiveness of the disclosure controls and procedures, as of the end
         of the period covered by this report based on such evaluation; and

         (c) Disclosed in this report any change in the registrant's internal
         control over financial reporting that occurred during the registrant's
         most recent fiscal quarter (the registrant's fourth fiscal quarter in
         the case of an annual report) that has materially affected, or is
         reasonably likely to materially affect, the registrant's internal
         control over financial reporting; and

     The registrant's other certifying officer(s) and I have disclosed, based on
     our most recent evaluation of internal control over financial reporting, to
     the registrant's auditors and the audit committee of the registrant's board
     of directors (or persons performing the equivalent functions):

         (a) All significant deficiencies and material weaknesses in the design
         or operation of internal control over financial reporting which are
         reasonably likely to adversely affect the registrant's ability to
         record, process, summarize and report financial information; and

         (b) Any fraud, whether or not material, that involves management or
         other employees who have a significant role in the registrant's
         internal control over financial reporting.

                             AS ADOPTED PURSUANT TO
                  SECTION 302 OF THE SARBANES-OXLEY ACT OF 2002

I, PAUL G. DRISCOLL, certify that:

     I have reviewed this Quarterly Report on Form 10-Q of Acme United
     Corporation;

     Based on my knowledge, this report does not contain any untrue statement of
     a material fact or omit to state a material fact necessary to make the
     statements made, in light of the circumstances under which such statements
     were made, not misleading with respect to the period covered by this
     report;

     Based on my knowledge, the financial statements, and other financial
     information included in this report, fairly present in all material
     respects the financial condition, results of operations and cash flows of
     the registrant as of, and for, the periods presented in this report;

     The registrant's other certifying officer(s) and I are responsible for
     establishing and maintaining disclosure controls and procedures (as defined
     in Exchange Act Rules 13a-15(e) and 15d-15(e)) for the registrant and have:

         (a) Designed such disclosure controls and procedures, or caused such
         disclosure controls and procedures to be designed under our
         supervision, to ensure that material information relating to the
         registrant, including its consolidated subsidiaries, is made known to
         us by others within those entities, particularly during the period in
         which this report is being prepared;

         (b) Evaluated the effectiveness of the registrant's disclosure controls
         and procedures and presented in this report our conclusions about the
         effectiveness of the disclosure controls and procedures, as of the end
         of the period covered by this report based on such evaluation; and

         (c) Disclosed in this report any change in the registrant's internal
         control over financial reporting that occurred during the registrant's
         most recent fiscal quarter (the registrant's fourth fiscal quarter in
         the case of an annual report) that has materially affected, or is
         reasonably likely to materially affect, the registrant's internal
         control over financial reporting; and

     The registrant's other certifying officer(s) and I have disclosed, based on
     our most recent evaluation of internal control over financial reporting, to
     the registrant's auditors and the audit committee of the registrant's board
     of directors (or persons performing the equivalent functions):

         (a) All significant deficiencies and material weaknesses in the design
         or operation of internal control over financial reporting which are
         reasonably likely to adversely affect the registrant's ability to
         record, process, summarize and report financial information; and

         (b) Any fraud, whether or not material, that involves management or
         other employees who have a significant role in the registrant's
         internal control over financial reporting.
