                First Manhattan Co. (“FMC”) hereby amends and supplements its statement on Schedule 13D with respect to the common stock, $1 par value (the “Common Stock”), of Snap-On Incorporated, a Delaware corporation (the “Issuer”). Except as amended and supplemented hereby, the information in the original Schedule 13D remains in full force and effect.

Item 5. Interest in Securities of the Issuer.

                As of April 25, 2001, FMC beneficially owned an aggregate of 5,065,491 shares of Common Stock of the Issuer, or 7.9% of the 64,238,603 shares of Common Stock of the Issuer that were outstanding as of February 26, 2001. Such 5,065,491 shares beneficially owned by FMC include 494,900 shares owned by general partners of FMC, as to which FMC had sole voting power and sole dispositive power with respect to 222,900 shares, shared voting power with respect to 97,500 shares and shared dispositive power with respect to 272,000 shares, and 4,570,591 shares owned by customers of FMC for whom FMC was authorized to vote or to exercise investment discretion, as to which FMC had sole voting power and sole dispositive power with respect to 61,500 shares, shared voting power with respect to 4,373,897 shares and shared dispositive power with respect to 4,509,091 shares. The general partners and customers of FMC that owned such shares had shared voting power and shared dispositive power with respect to the shares owned by them and the sole right to receive dividends and the proceeds of sale of such shares. None of such general partners or customers had shared voting power or shared dispositive power with respect to 5% or more of the outstanding shares of the class.

                The number of shares of Common Stock outstanding as of February 26, 2001 includes 57,795,506 shares which the Issuer reported as outstanding as of that date on the cover page of its Form 10-K report for the year ended December 30, 2000 and 6,443,097 shares which were owned by a Grantor Stock Trust at December 31, 2000, according to a statement on Schedule 13G filed by the Trust on March 22, 2001. Although the Issuer did not include such 6,443,097 shares as outstanding for purposes of the cover page of the Form 10-K report, the Issuer claims that such shares are entitled to be voted at stockholders’ meetings and may be sold by the Trustee of the Grantor Stock Trust under certain circumstances, and accordingly FMC believes that such shares should be considered outstanding for purposes of calculating the percentage of the class of securities with respect to which FMC has voting power or dispositive power.

                Set forth on Schedule I hereto are transactions effected by FMC during the sixty days preceding the filing of this statement in Common Stock of the Issuer with respect to which FMC may be deemed to be or to have been a beneficial owner for purposes of Section 13(d) of the Securities Exchange Act of 1934. All of such transactions were for the accounts of customers of FMC.
