Title: I'm stumped on this one!
Post by: coolford on March 13, 2018, 03:49:14 PM
Item is a little over 4 inches long and appears to be rosewood.  On the end it says No.2, Pat Dec 15 85 and June 24 90.  Note groove on both sides of the working end.  Back of handle has a nut which is holding in the working end.  Was mixed in with bunch of planes.

Could it be part of a fly-tying rig?

Hello, Coolford. Could it be a haft? Or maybe this one, Knife Blade Holder Pat. No. 332548  ??? Regards, Lou

Looked at the patent, somewhat like it but not the same although the date is correct.  Got to looking at the end, couldn't figure how it would take a knife blade.  Then the light turned on, what if it held a broken knife blade?  Took it out to the shop, got a narrow needle point plier and pulled on the center section and out came a broken knife blade.  And now we know----thanks.

Yes, I recognized the "jaws" as similar to a knife I have.  Is it just a utility knife or does it have a special purpose?

I have that very tool, and it came with a knife blade.  The "wings" help you thread the assembly into the handle to tighten up the blade.  Similar concept to XActo knives, but with more class.

I. P. Hyde and C. S. Osborne both called them extension blade handles.  The handles came in different styles, listed as bevel, sharp, lance, and curve.  Osborne lists them for cutting leather and similar materials.  Hyde lists them for cutting mat board and heavy paper.  I used 1953 Hyde catalog and 1950s (estimated) Osborne catalogs for reference.

Thanks for all the info, when I pulled the broken blade out it was pointed on the other end.  Maybe they made blades double ended so when they got dull you could turn them around.  I'm surprised that they were made as late as the 50's since they used fancy wood for the handle.
