CUSIP NO. 784413106

The following constitutes Amendment No. 34 to the Schedule 13D filed by the undersigned (“Amendment No. 34”). This Amendment No. 34 amends the Schedule 13D as specifically set forth herein.

Item 1.

Security and Issuer.

Item 3.

Source and Amount of Funds or Other Consideration.

Item 4.

Purpose of Transaction.

Items 1, 3 and 4 are hereby amended to add the following:

As previously disclosed, on April 6, 2016, the Issuer entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Handy & Harman Ltd., a publicly-traded NASDAQ company and an affiliate of Steel Holdings (“Parent”), Handy & Harman Group Ltd., a Delaware corporation and a wholly owned subsidiary of Parent (“AcquisitionCo”), and SLI Acquisition Co., a Delaware corporation and a wholly owned subsidiary of AcquisitionCo (“Merger Sub”), pursuant to which, among other things, Parent and AcquisitionCo agreed to cause Merger Sub to make a cash tender offer (the “Offer”) to purchase all of the outstanding Shares of the Issuer, at a purchase price of $40.00 per Share in cash (the “Offer Price”). Concurrently with the execution of the Merger Agreement, DGT entered into a Tender Agreement with the Issuer, Parent, AcquisitionCo and Merger Sub pursuant to which it agreed to promptly tender, and not withdraw, 994,840 Shares owned directly by DGT into the Offer. On April 21, 2016, Merger Sub commenced the Offer to purchase all of the outstanding Shares of the Issuer for the Offer Price.

The Offer expired as scheduled at 5:00 p.m., New York City time, on May 31, 2016. On May 31, 2016, all conditions to the Offer having been satisfied, Merger Sub accepted for payment all Shares that were validly tendered and not validly withdrawn pursuant to the Offer, including the 994,840 Shares owned directly by DGT, 7,507 Shares owned directly by Warren G. Lichtenstein, 17,000 Shares owned directly by Glen M. Kassan and 750 Shares beneficially owned by Jack L. Howard.

On June 1, 2016, pursuant to the terms of the Merger Agreement and in accordance with Section 251(h) of the General Corporation Law of the State of Delaware (the “DGCL”), Merger Sub merged with and into the Issuer (the “Merger”), with the Issuer being the surviving corporation (the “Surviving Corporation”) and continuing as a wholly owned subsidiary of AcquisitionCo.

At the effective time of the Merger (the “Effective Time”) and pursuant to the terms and conditions of the Merger Agreement, (i) each issued and outstanding share of common stock, par value $0.01 per share, of Merger Sub, of which 100 shares were issued and outstanding as of June 1, 2016, was converted into one validly issued, fully paid and nonassessable share of the Surviving Corporation, and (ii) each Share issued and outstanding immediately prior to the Effective Time (other than Shares held by the Issuer, any of its subsidiaries, Parent, AcquisitionCo or Merger Sub or held by stockholders of the Issuer who have properly and validly perfected their statutory rights of appraisal in respect of such Shares in accordance with Section 262 of the DGCL), including 10 Shares owned directly by Anthony Bergamo that were not tendered into the Offer, was cancelled and converted into the right to receive the Offer Price, without interest thereon and subject to any required tax withholding. In addition, under the terms of the Merger Agreement, all Issuer equity awards (that is, stock options, restricted stock units and restricted stock) outstanding at the Effective Time of the Merger, whether vested or unvested or exercisable or unexercisable, were cancelled and converted into the right to receive an amount in cash (less applicable tax withholdings) equal to the product of the Offer Price (or in the case of stock options, the Offer Price less the applicable exercise price) and the number of Shares subject to the award or issuable upon exercise thereof immediately prior to the Effective Time of the Merger, including 6,000 restricted Shares owned directly by each of Messrs. Lichtenstein and Kassan. The Shares will no longer be listed on the NYSE MKT and will be deregistered under the Securities Exchange Act of 1934, as amended.

CUSIP NO. 784413106

The aggregate consideration paid by AcquisitionCo in the Offer and Merger was approximately $163.8 million, without giving effect to related transaction fees and expenses.

Item 5.

Interest in Securities of the Issuer.

Items 5(a)-(c) are hereby amended and restated to read as follows:

(a) As a result of the Merger, Parent owned (indirectly through AcquisitionCo) 100 Shares of the Issuer, representing 100% of the issued and outstanding Shares as of the date hereof. Solely by virtue of SPHG Holdings’ ownership of approximately 70% of the outstanding shares of common stock of Parent and the relationships discussed in further detail in Item 2, each of SPHG Holdings, Steel Holdings, SPHG and Steel Holdings GP may be deemed to beneficially own the Shares beneficially owned by Parent. Each of SPHG Holdings, Steel Holdings, SPHG and Steel Holdings GP disclaims beneficial ownership of such Shares. As a result of the Offer and Merger, no other Reporting Person nor any individual listed on Schedule A beneficially owns any Shares.

(b) Solely by virtue of SPHG Holdings’ ownership of approximately 70% of the outstanding shares of common stock of Parent and the relationships discussed in further detail in Item 2, each of SPHG Holdings, Steel Holdings, SPHG and Steel Holdings GP may be deemed to have shared voting and dispositive power with respect to the Shares beneficially owned by Parent.

(c) On May 4, 2016, the Issuer awarded 3,000 restricted Shares to each of Messrs. Lichtenstein and Kassan in their capacities as directors of the Issuer. Except for such awards and the transactions relating to the consummation of the Offer and Merger described above, there have been no transactions by the Reporting Persons in the securities of the Issuer during the past 60 days.
