              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. 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

The Company has been involved in certain environmental and other matters.
Additionally, the Company is involved in a legal action that is still in its
preliminary stage. Based on information available, the Company 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:

</TABLE>

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 June 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 June 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 six months of 2004, the Company issued 176,000 shares of common
stock with proceeds of $625,060 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 repurchase of 16,000
shares by the Company within six months of the original option exercise.


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 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. will enforce the letter of credit and drawdown the funds. The letter of
credit liability was recorded in other current liabilities as of June 30, 2004.
Included in the accompanying Statement of Operations are the operations of the
acquired business, which resumed on June 1, 2004. In accordance with Regulation
S-X, proforma information is not provided because of the immateriality of the
transaction.

Note 9 -- Abandonment 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 Six Months Ended June 30, 2004


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 June 30, 2004 were $12,298,000
compared with $10,142,000 for 2003, a 21% increase. Net sales for the first six
months of 2004 were $20,865,000 compared with $17,331,000 for 2004, a 20%
increase. Excluding the favorable effect of currency gains in Canada and Europe,
net sales for the first six months increased 18%. The sales increase was mainly
driven by an 18% increase in the U.S. due to market share gains and new product
launches. Europe and Canada sales were up 9% in local currency. The new business
in Hong Kong generated $437,000 in the first six months of 2004.


Gross Profit

The gross profit for the second quarter of 2004 was $5,519,000 (44.9% of net
sales) compared to $3,921,000 (38.7% of net sales) for the second quarter of
2003. Gross profit for the first six months of 2004 was 44.3% of net sales
compared to 39.3% 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 second quarter of
2004 were $3,579,000 (29% of net sales) compared with $2,906,000 (29% of net
sales) for the same period of 2003, an increase of $673,000. SG&A expenses were
31% of net sales for the first six months of 2004 versus 30% 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 six months of 2004 was $85,000, compared with
$152,000 for 2003, a $67,000 decrease. This is mainly attributable to the
decline in debt.


Other Expense

Net other expense was $74,000 in the first six months of 2004 compared to
$135,000 in the first six months of 2003. The change from 2003 primarily relates
to the settlement of a $175,000 lawsuit in Germany in March of 2003 partially
offset by the write-off of obsolete equipment in the second quarter of 2004.


Income Before Income Taxes

Income before income taxes was $1,820,000 in the second quarter of 2004 compared
with $958,000 in the second quarter of 2003, an increase of $862,000. Income
before income taxes was $2,530,000 for the first six months of 2004 compared
with $1,310,000 in the first six months of 2003, an improvement of $1,220,000.
Pretax income for North America and Asia increased by approximately $1.2
million. Despite a 15% increase in sales, the European operations had a slightly
higher loss (exclusive of the one time expense of $175,000) in the first six
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 six months of 2004 was 42% compared to 47%
in 2003. 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 second quarter of 2004 was $1,075,000, or 29 cents per share
(diluted), compared to a net income of $615,000, or 17 cents per share (diluted)
for the same period of 2003. Net income for the first six months of 2004 was
$1,468,000, or 40 cents per share (diluted), compared to a net income of
$693,000, or 20 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 Six Months Ended June 30, 2004


Financial Condition

Liquidity and Capital Resources

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

                                          June 30, 2004        December 31, 2003
                                       ------------------     ------------------

Working capital.......................      $12,499,000           $10,778,000
Current ratio.........................        2.36 to 1             2.68 to 1
Long-term debt to equity ratio........            21.4%                 27.0%


During the first six months of 2004, total debt increased by $478,000 compared
to total debt at December 31, 2003 principally as a result of net additional
short-term borrowings to fund inventory purchases in anticipation of next
quarter's seasonal sales volume and seasonal collection terms which are longer
during the second and third quarters.

The Company has a revolving loan agreement, which allows for borrowings up to a
maximum of $10,000,000 based on a formula, which applies specific percentages to
balances of accounts receivable and inventory. Interest is payable monthly and
is charged at the LIBOR rate plus 1.75 percent. As of June 30, 2004, $4,643,612
was outstanding and $5,356,388 was available for borrowing under this agreement.
Maturities of long-term debt follow: 2004 - $2,873,000, 2005 - $2,533,000. All
outstanding borrowings are due on July 31, 2005.

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.

     4.   The registrant's other certifying officers and I are responsible for
          establishing and maintaining disclosure controls and procedures (as
          defined in Exchange Act Rules 13a-14 and 15d-14) for the registrant
          and have:

          a)   designed such disclosure controls and procedures 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
               quarterly report is being reported;
          b)   evaluated the effectiveness of the registrant's disclosure
               controls and procedures as of June 30, 2004; and
          c)   presented in this quarterly report our conclusions about the
               effectiveness of the disclosure controls and procedures based on
               our evaluation as of June 30, 2004;

     5.   The registrant's other certifying officers and I have disclosed, based
          on our most recent evaluation, to the registrant's auditors and the
          audit committee of registrant's board of directors:

          a)   all significant deficiencies in the design or operation of
               internal controls which could adversely affect the registrant's
               ability to record, process, summarize and report financial data
               and have identified for the registrant's auditors any material
               weaknesses in internal controls; and
          b)   any fraud, whether or not material, that involves management or
               other employees who have significant role in the registrant's
               internal controls; and

     6.   The registrant's other certifying officers and I have indicated in
          this quarterly report whether there were significant changes in
          internal controls or in other factors that could significantly affect
          internal controls subsequent to the date of our most recent
          evaluation, including any corrective actions with regard to
          significant deficiencies and material weaknesses.
