CUSIP No. 420089 10 4  Page 9  of  13  Pages

Introduction.

     Pursuant to Rule 13d-1(k), this Amendment No. 3 to Schedule 13D (the “Amendment”) is filed by Norman C. Harbert, the Harbert Family Limited Partnership (the “HFLP”), the Harbert Foundation (the “Foundation”), Ronald E. Weinberg, the Weinberg Family Limited Partnership (the “WFLP”), Byron S. Krantz and the Krantz Family Limited Partnership (the “KFLP”) (collectively, the “Reporting Persons”) relating to shares of Class A common stock, par value $0.01 per share, of Hawk Corporation, a Delaware corporation (“Hawk”).

Item 4. Purpose of Transaction.

     Item 4 is amended and supplemented as follows:

     As previously disclosed by the Reporting Persons in its Amendment No. 2 to Schedule 13D filed on July 6, 2010 with the Securities and Exchange Commission (“SEC”) and as previously disclosed on the Form 8-K filed by Hawk on July 1, 2010 with the SEC, Hawk issued a press release on July 1, 2010 announcing that it had commenced a process to explore strategic alternatives, including a possible sale of Hawk. In connection with the exploration of strategic alternatives, Hawk’s Board of Directors formed a Special Committee of the Board, consisting solely of independent directors. This Special Committee retained Harris Williams & Co., as its financial advisor.

     On October 14, 2010, as a result of the exploration of strategic alternatives, Hawk announced that it had entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Carlisle Companies Incorporated, a Delaware corporation (“Carlisle”), and HC Corporation, a Delaware corporation and a wholly-owned subsidiary of Carlisle (“Merger Sub”). Pursuant to the Merger Agreement, Carlisle and Merger Sub will commence a tender offer (the “Offer”) to purchase all of the issued and outstanding shares of Hawk’s Class A common stock (“Hawk Common Stock”), including the associated Rights (as defined in the Merger Agreement) (each, a “Share” and, collectively, the “Shares”), at a purchase price of $50.00 per share in cash (the “Offer Price”). The Offer will be followed by a merger of Merger Sub with and into Hawk (the “Merger”) with Hawk surviving the Merger as a wholly-owned subsidiary of Carlisle. At the effective time of the Merger, all remaining outstanding Shares not tendered in the Offer (other than (1) Hawk Common Stock owned by Carlisle, Merger Sub, Hawk and its subsidiaries and (2) Shares for which appraisal has been properly demanded under Delaware law) will be acquired for cash at the Offer Price and on the terms and conditions in the Merger Agreement (the “Merger Consideration”).

     Hawk’s press releases with respect to the Merger Agreement were filed as Exhibit 99.1 and Exhibit 99.2 to Hawk’s Form 8-K filed on October 18, 2010 with the SEC and are incorporated herein by reference.

     Concurrently with the execution of the Merger Agreement, and as a condition and inducement to Carlisle entering into the Merger Agreement, each of Messrs. Weinberg, Harbert and Krantz entered into a Tender and Voting Agreement with Carlisle and Merger Sub (the “Tender Agreements”). Pursuant to the Tender Agreements, each of Messrs. Weinberg, Harbert and Krantz has agreed, among other things, (1) to tender all of his Shares in the Offer; (2) in the event a vote of the Company’s stockholders is required in furtherance of the Merger Agreement

CUSIP No. 420089 10 4  Page 10  of  13  Pages

or the transactions contemplated thereby, including the Merger, he will vote all of his Shares (to the extent any such Shares are not purchased in the Offer) in favor of the approval of the Merger and the adoption of the Merger Agreement and against any proposal inconsistent therewith; and (3) to consent to the redemption by the Company of all of his shares of the Company’s Series D preferred stock. The Tender Agreements will automatically terminate upon the termination of the Merger Agreement in accordance with its terms.

     The description of the Tender Agreements does not purport to be complete and is qualified in its entirety by reference to the Tender Agreements. Copies of the Tender Agreements are filed herewith as Exhibit 7.1, Exhibit 7.2, and Exhibit 7.3 and incorporated by reference herein.

     The Merger Agreement provides that, at the effective time of the Merger, (1) each outstanding unexercised stock option of Hawk’s will fully vest and be cancelled, and (2) each option holder will be entitled to receive from Hawk in settlement of each option a single lump sum payment equal to the net amount of (i) the product of (A) the excess, if any, of the Merger Consideration over the exercise price per share of such option, multiplied by (B) the number of shares subject to such option, less (ii) any tax required to be withheld. In connection with this provision, certain of Hawk’s option holders have entered into letters with Hawk regarding the cancellation of their options at the effective time of the Merger, in accordance with the foregoing provision of the Merger Agreement (the “Option Cancellation Letters”). Each of Messrs. Weinberg and Krantz entered into an Option Cancellation Letter in connection with the Merger Agreement.

     The description of the Option Cancellation Letters does not purport to be complete and is qualified in its entirety by reference to the Form of the Option Cancellation Letter. The Form of Option Cancellation Letter for Messrs. Weinberg and Krantz is filed herewith as Exhibit 7.4 and incorporated by reference herein.

Item 5. Interest in Securities of the Issuer.

     Items 5(a), (b) and (c) are amended and supplemented as follows:

     (a) According to the Merger Agreement, there are currently 7,759,063 shares of Hawk Common Stock outstanding as of October 14, 2010.

     Mr. Harbert beneficially owns 1,096,506 shares of Hawk Common Stock, including 2,081 shares held in his 401(k) plan, 1,000,511 shares held by the HFLP and 35,000 shares held by the Foundation, or 14.1% of the outstanding Hawk Common Stock. The HFLP beneficially owns 12.9% of the outstanding Hawk Common Stock. The Foundation beneficially owns 0.5% of the outstanding Hawk Common Stock.

     Mr. Weinberg beneficially owns 1,409,965 shares of Hawk Common Stock, including 1,083,153 shares held by the WFLP and a currently exercisable option to purchase 135,967 shares of Hawk Common Stock or 17.9% of the outstanding Hawk Common Stock, assuming exercise of the option held by Mr. Weinberg. The WFLP beneficially owns 14.0% of the outstanding Hawk Common Stock.

CUSIP No. 420089 10 4  Page 11  of  13  Pages

     Mr. Krantz beneficially owns 292,940 shares of Hawk Common Stock, including 243,876 shares held by the KFLP and a currently exercisable option to purchase 8,968 shares of Hawk Common Stock, or 3.8% of the outstanding Hawk Common Stock, assuming exercise of the option held by Mr. Krantz. The KFLP beneficially owns 3.1% of the outstanding Hawk Common Stock.

     Together, the Reporting Person own 2,799,411 shares of Hawk Common Stock, including currently exercisable options to purchase 144,935 shares of Hawk Common Stock, or 35.4% of the outstanding Hawk Common Stock, assuming exercise of the options held by Messrs. Weinberg and Krantz. Each Reporting Person disclaims beneficial ownership of the shares of Hawk Common Stock and the options held by each other Reporting Person.

     (b) Due to the terms of the Tender Agreements, each Reporting Person may be deemed to have shared power to vote, or direct the voting of, and shared power to dispose, or to direct the disposition of, the shares of Hawk Common Stock beneficially owned by such Reporting Person with Carlisle for the limited purposes described in Item 4 above.

     In addition, Mr. Harbert, as chairman of the board of trustees of the Foundation, has shared power to vote, or to direct the voting of, and shared power to dispose, or to direct the disposition of, the shares of Hawk Common Stock owned by the Foundation. The Foundation has sole power to vote, or to direct the voting of, and sole power to dispose, or to direct the disposition of, the shares of Hawk Common Stock owned by it.

     (c) None of the Reporting Persons have effected any transactions in the Hawk Common Stock in the past sixty days.

     1. As of the date hereof, the Stockholder is the beneficial owner of the number of shares of Company Common Stock set forth opposite the name of the Stockholder on Annex A hereto (excluding shares of Common Stock deemed to be beneficially owned as a result of holding Options) (such shares on Annex A, together with any shares of Company Common Stock acquired by the Stockholder after the date hereof, whether as a result of the exercise of Options or otherwise, "Owned Common Shares”);

     2. As of the date hereof, the Stockholder is the beneficial owner of the number of shares of Company Series D Preferred Stock set forth opposite the name of the Stockholder on Annex A hereto (such shares on Annex A, together with any shares of Company Series D Preferred Stock acquired by the Stockholder after the date hereof, “Owned Preferred Shares”);

     4. Parent, Merger Sub, and the Company are simultaneously with the execution of this Agreement entering into an Agreement and Plan of Merger, dated as of the date of this Agreement (as it may be amended from time to time in accordance with its terms, the “Merger Agreement”), providing for, among other things, Merger Sub to commence a cash tender offer (the “Offer”) to acquire all of the outstanding Shares of the Company, followed by the subsequent merger of Merger Sub with and into the Company, with the Company surviving the merger as a wholly owned subsidiary of Parent, in each case, on the terms and subject to the conditions set forth in the Merger Agreement;

     5. As a condition to Parent’s and Merger Sub’s willingness to enter into and perform its obligations under the Merger Agreement, Parent and Merger Sub have required that the Stockholder agree, and the Stockholder has agreed, on the terms and subject to the conditions set forth herein, (i) to tender in the Offer (and not withdraw) all of the Stockholder’s Owned Common Shares, (ii) that, in the event that a vote of the Company’s stockholders is required in furtherance of the Merger Agreement or the transactions contemplated thereby, including the Merger, the Stockholder will vote all of the Owned Common Shares (to the extent any Owned Common Shares are not purchased in the Offer) and all Owned Preferred Shares (to the extent any Owned Preferred Shares are not redeemed by the Company prior to such date) in favor of the approval of the Merger and the adoption of the Merger Agreement, (iii) to consent to the

redemption by the Company of all of the Owned Preferred Stock and (iv) to take the other actions described in this Agreement; and

     6. The Stockholder desires to express his support for the Merger Agreement and the transactions contemplated thereby, including the Offer and the Merger.

     NOW, THEREFORE, in consideration of the premises and for other good and valuable consideration given to each party hereto, the receipt and adequacy of which are hereby acknowledged, the parties agree as follows:

     1. Agreement to Tender and Vote; Irrevocable Proxy.

          1.1 Agreement to Tender. The Stockholder agrees that, as promptly as practicable after the commencement of the Offer, and in any event no later than the tenth Business Day following the commencement of the Offer, the Stockholder shall irrevocably tender into the Offer all of the Owned Common Shares owned by the Stockholder, free and clear of all Liens. If the Stockholder acquires any Owned Common Shares after the tenth Business Day following the commencement of the Offer (including during any subsequent offering period, if any), then the Stockholder shall irrevocably tender into the Offer such Owned Common Shares within three Business Days after the date that the Stockholder shall acquire such Owned Shares. The Stockholder agrees that, once the Owned Common Shares are tendered into the Offer, the Stockholder shall not withdraw the tender of such Owned Common Shares unless the Offer shall have been terminated or shall have expired, in each case, prior to the Acceptance Time and in accordance with the terms of the Merger Agreement, or unless the Merger Agreement has been terminated.

          1.2 Agreement to Vote. The Stockholder hereby agrees that, during the term of this Agreement, at any meeting of the stockholders of the Company (including the Company Stockholders Meeting), however called, or any adjournment or postponement of such meeting, the Stockholder shall be present (in person or by proxy) and vote (or cause to be voted) all of the Owned Common Shares (to the extent the Owned Common Shares are not purchased in the Offer) and all of the Owned Preferred Shares (to the extent the Owned Preferred Share are not redeemed by the Company), and cause to be voted any shares of Company Common Stock or Company Series D Preferred Stock with respect to which the Stockholder holds the right to direct the voting pursuant to the Stockholders’ Agreement (the “Beneficial Voting Rights Shares”):

               (a) in favor of adoption of (1) the Merger Agreement and all the transactions contemplated by the Merger Agreement, including the Merger, and (2) any other matter that is required to facilitate the consummation of the transactions contemplated by the Merger Agreement and, in connection with the Merger Agreement, to execute any documents which are necessary or appropriate in order to effectuate the foregoing; and

               (b) against (1) any Acquisition Proposal and any agreement or arrangement related to such Acquisition Proposal, and (2) any action or agreement that would impair the ability of Parent and the Merger Sub to complete the Offer or the Merger, or the ability of the Company to consummate the Merger, in any material respect or that would

2

otherwise be inconsistent with or prevent, impede or delay the consummation of the transactions contemplated by the Merger Agreement in any material respect.

     NOW, THEREFORE, in consideration of the premises and for other good and valuable consideration given to each party hereto, the receipt and adequacy of which are hereby acknowledged, the parties agree as follows:

     1. Agreement to Tender and Vote; Irrevocable Proxy.

          1.1 Agreement to Tender. The Stockholder agrees that, as promptly as practicable after the commencement of the Offer, and in any event no later than the tenth Business Day following the commencement of the Offer, the Stockholder shall irrevocably tender into the Offer all of the Owned Common Shares owned by the Stockholder, free and clear of all Liens. If the Stockholder acquires any Owned Common Shares after the tenth Business Day following the commencement of the Offer (including during any subsequent offering period, if any), then the Stockholder shall irrevocably tender into the Offer such Owned Common Shares within three Business Days after the date that the Stockholder shall acquire such Owned Shares. The Stockholder agrees that, once the Owned Common Shares are tendered into the Offer, the Stockholder shall not withdraw the tender of such Owned Common Shares unless the Offer shall have been terminated or shall have expired, in each case, prior to the Acceptance Time and in accordance with the terms of the Merger Agreement, or unless the Merger Agreement has been terminated.

          1.2 Agreement to Vote. The Stockholder hereby agrees that, during the term of this Agreement, at any meeting of the stockholders of the Company (including the Company Stockholders Meeting), however called, or any adjournment or postponement of such meeting, the Stockholder shall be present (in person or by proxy) and vote (or cause to be voted) all of the Owned Common Shares (to the extent the Owned Common Shares are not purchased in the Offer) and all of the Owned Preferred Shares (to the extent the Owned Preferred Share are not redeemed by the Company), and cause to be voted any shares of Company Common Stock or Company Series D Preferred Stock with respect to which the Stockholder holds the right to direct the voting pursuant to the Stockholders’ Agreement (the “Beneficial Voting Rights Shares”):

               (a) in favor of adoption of (1) the Merger Agreement and all the transactions contemplated by the Merger Agreement, including the Merger, and (2) any other matter that is required to facilitate the consummation of the transactions contemplated by the Merger Agreement and, in connection with the Merger Agreement, to execute any documents which are necessary or appropriate in order to effectuate the foregoing; and

               (b) against (1) any Acquisition Proposal and any agreement or arrangement related to such Acquisition Proposal, and (2) any action or agreement that would impair the ability of Parent and the Merger Sub to complete the Offer or the Merger, or the ability of the Company to consummate the Merger, in any material respect or that would

otherwise be inconsistent with or prevent, impede or delay the consummation of the transactions contemplated by the Merger Agreement in any material respect.

          1.3 Irrevocable Proxy. The Stockholder hereby irrevocably grants to, and appoints, Parent and any designee of Parent and each of Parent’s officers, as Stockholder’s attorney, agent and proxy with full power of substitution and resubstitution, to the full extent of the Stockholder’s voting rights with respect to the Owned Common Shares, the Owned Preferred Shares and the Beneficial Voting Rights Shares, to vote all the Owned Common Shares and the Owned Preferred Shares or grant a consent or approval, at any meeting of the stockholders of the Company (including the Company Stockholders Meeting) and in any action by written consent of the stockholders of the Company, until the earlier of (a)(1) the Acceptance Time (with respect to Shares) or (2) the Effective Time (with respect to Company Series D Preferred Stock) or (b) the date of termination of the Merger Agreement, on the matters described in Section 1.2 and in accordance therewith. THIS PROXY AND POWER OF ATTORNEY ARE IRREVOCABLE AND COUPLED WITH AN INTEREST SUFFICIENT IN LAW TO SUPPORT AN IRREVOCABLE PROXY AND, TO THE EXTENT PERMITTED UNDER APPLICABLE LAW, SHALL BE VALID AND BINDING ON ANY PERSON TO WHOM THE STOCKHOLDER MAY TRANSFER ANY OWNED COMMON SHARES OR OWNED PREFERRED SHARES OR HIS RIGHT TO VOTE THE BENEFICIAL VOTING RIGHTS SHARES. The Stockholder hereby revokes all other proxies and power of attorneys, with respect to all of the Owned Common Shares or the Owned Preferred Shares that may have heretofore been appointed or granted with respect to any matters covered by Section 1.2, and no subsequent proxy (whether revocable or irrevocable) or power of attorney shall be given by the Stockholder, except as required by any letter of transmittal in connection with the Offer. The Stockholder agrees to execute any further agreement or form reasonably necessary or appropriate to confirm and effectuate the grant of the proxy contained herein. Such proxy shall automatically terminate upon the valid termination of this Agreement in accordance with Section 6.1.

     2. Consent to Redemption of Company Series D Preferred Stock. The Stockholder hereby consents to the redemption by the Company, immediately prior to the Acceptance Time, of all of the Company Series D Preferred Stock in accordance with Section 8(a) of the Certificate of Designations of the Series D Preferred Stock.

Re:  Your Options under the Hawk Corporation 1997 Stock Option Plan and/or the Hawk Corporation Amended and Restated 2000 Long-Term Incentive Plan

Dear [________]:

As you know, Hawk Corporation is negotiating an agreement and plan of merger with Carlisle Companies Incorporated (“Carlisle”) and HC Corporation (the “Merger Agreement”). The Merger Agreement will provide, among other things, that Carlisle will commence a tender offer to purchase all of the outstanding shares of Class A common stock of Hawk (the “Shares”) at a price of $50.00 in cash per share (the “Offer”). Following the consummation of the Offer, HC Corporation would merge with and into Hawk and Hawk will become a wholly-owned subsidiary of Carlisle and each share of Class A common stock of Hawk that was not tendered in the Offer would thereupon be cancelled and converted into the right to receive $50.00 in cash (the “Merger”). The Merger would affect the stock options you have been granted (the “Options”) under the Hawk Corporation 1997 Stock Option Plan or the Hawk Corporation Amended and Restated 2000 Long-Term Incentive Plan (the “Plans”). The treatment of your Options in connection with the Merger is explained below.

Under the Merger Agreement, your Options will be cancelled and you will receive a single lump sum cash payment equal to the net value of all your outstanding Options, whether vested or unvested. In other words, for each Share you are eligible to purchase under an Option agreement, you would be entitled to receive $50.00 less the per share exercise price, less applicable federal and state withholding taxes (the “Cash-Out Payment”). For example, if on the date the Merger is completed you hold an Option to purchase 100 Shares and the exercise price is $5.00 per Share, you would receive a Cash-Out Payment equal to $45.00 per Option Share ($50.00 – $5.00) for a total of $4,500.00, less applicable withholding taxes.

According to our records, upon cancellation of your Options, you would be entitled to receive a Cash-Out Payment of $___________, less applicable withholding taxes. Exhibit A attached hereto shows each of your currently outstanding Options, and how your payment was calculated. Please carefully review Exhibit A and contact Tom Gilbride, at tgilbride@hawkcorp.com or 216-861-3559 if you believe it does not accurately reflect the number of Options you hold or the per share exercise price of the Options. The Cash-Out Payment will be made promptly following the completion of the Merger. In the event that the Merger is not completed, your Options will not be cancelled and you will not receive any cash payment for them.

Finally, please note that prior to the closing of the Offer, you may exercise your vested Options in accordance with their terms and the standard procedures for exercising Option established by Hawk, including Hawk’s trading window policy, the insider trading policy and Federal securities laws in general. All of your Options will vest upon the closing of the Offer and you may exercise your vested Options after the Offer, and prior to the Merger, in accordance with their terms and the standard procedures for exercising Option established by Hawk, including Hawk’s trading window policy, the insider trading policy and Federal securities laws in general. The current terms and standard procedures applicable to your Options also continue to apply in the event you die or otherwise terminate your employment or relationship with Hawk prior to the closing of the Merger. If you wish to exercise vested Options prior to the Merger, please consult your personal tax advisor. If you are a company insider, remember that all such exercises must be pre-cleared by Tom Gilbride.

If you agree to the cancellation of your Options in exchange for your Cash-Out Payment, please sign this letter below and return it to me as soon as possible.

Sincerely,

HAWK CORPORATION

Thomas A. Gilbride
Vice President — Finance
