    I have no idea what this instrument is used for. A turned wooden handle with a cone-shaped attachment, slotted on one side where the knife blade fits. The blade hinges open with the cutting side on the inside. This instrument is 7.25" long. It is made by Will & Finck the famous San Francisco knife makers in business from 1863-1932.

    Any information on what this instrument is used for would be greatly appreciated.

      Strange one ;-)

      It is a cork boring tool sharpener, it sharpens the tubes that put holes in corks for laboratory use. A nice find.

      Wow rustfarm! A wealth of knowledge!

      I'm impressed Rust!

      Thanks, I also collect odd tools that perform simple tasks, but often defy logic in their use. I might post a couple in the near future.

      Thanks Rustfarm - it all makes sense when I look at the tool now! Quite interesting.

      I have one of these as stated earlier and have since studied it as a possible cork cutter sharpening tool. Bottom line , I don't think that's correct. I know something about metal working and the blade on this tool is simply not strong enough to effectively cut metal to sharpen the edge of a metal cylindrical cutting tool.

      I was wrong earlier. It is a cork tool sharpener, found an advertisement for a more modern version.
