This Amendment No. 5 to Schedule 13D amends and supplements the Schedule 13D filed by the Reporting Persons with respect to the Common Stock, par value $0.0001 per share (“Common Stock”), of Symmetry Surgical, Inc., a Delaware corporation (the “Issuer”). Except as set forth below, all previous Items remain unchanged. Capitalized terms used herein but not defined herein shall have the meanings given to them in the Schedule 13D, as amended, filed with the Securities and Exchange Commission. Each of the Reporting Persons hereby expressly disclaims membership in a “group” under the Securities Exchange Act of 1934 with respect to the securities reported herein, and this Schedule 13D shall not be deemed to be an admission that any such Reporting Person is a member of such a group. Each of the Reporting Persons hereby expressly disclaims beneficial ownership of the securities reported herein, other than to the extent of its pecuniary interest therein, and this Schedule 13D shall not be deemed to be an admission that any such Reporting Person is the beneficial owner of the securities reported herein for purposes of the Securities Exchange Act of 1934 or for any other purpose.

Item 5. Interest in Securities of the Issuer

Item 5 is hereby supplemented as follows:

Effective July 1, 2016, the Issuer consummated its merger with Symmetry Surgical Holdings, Inc., a Delaware corporation (“Holdings”), and Symmetry Acquisition Corp., Inc., a Delaware corporation and wholly-owned subsidiary of Holdings (“Merger Sub”), contemplated by the Agreement and Plan of Merger (“Merger Agreement”) by and among the Issuer, Holdings, and Merger Sub (the “Merger”). As contemplated by the Merger Agreement, at the effective time of the Merger on July 1, 2016, each issued and outstanding share of Common Stock (including shares of Common Stock held by the Reporting Persons) was automatically cancelled and converted into the right to receive $13.10 in cash. Accordingly, effective July 1, 2016, the Reporting Persons are no longer the beneficial owners of any shares of Common Stock as a result of the consummation of the Merger in accordance with the terms of the Merger Agreement.
