Frank Bostner’s Tools

Treasure Trove

These hammers were found tucked away in a large metal box underneath the workbench in Frank Bostner’s shop, which had stood undisturbed for almost forty years, until Easter Sunday 2014.

In this group we have a 16 oz. Full-Finish No. 95 Machinists’ Ball Pein with the old-style decal that includes the model number. On either side we have smaller ball pein hammers with a thick oil finish on their heads and linseed oil on their second-growth hickory handles. As we’ll see, many of Frank’s hammers have this same finish.

On May 1, 1943 the company published Price List No. 26 which introduced new 800-series model numbers for the “Government Black” versions of the hammers they were offering in accordance with War Production Board Limitation Order No. L 157. This is the only finish produced during WWII, or at least the later half of it. Undoubtedly Frank was intimately involved in formulating and applying this finish. He certainly saved many fine examples.

These two hammers may be the most interesting find in the entire trove. They are not Cheney hammers. They are Triple-Claw hammers from the Chisel Claw Hammer Company of Hoboken, New Jersey. Hachig A. Ayvad was granted U.S. Patent 1,773,931 on 26 Aug 1930 for this unique hammer design. It had been speculated, based on the shape of their handles, that Cheney manufactured Ayvad’s hammer. Finding not one, but two, out of a collection otherwise exclusively from the Henry Cheney Hammer Company, virtually proves this hunch to be correct — clearly Frank Boster was making both Cheney and Ayvad hammers.
