Any additional info on this odd letter openner??? I bought it at a yard sale.
Might have to zoom in to read advertising on the handle. Reads as follows:

White Eagle Rawhide Mfg. Co. Inc.
Drum Heads & Artificial Limb Rawhide
1652 McHenry St. - Chicago
Armitage 0872

 

[Squirrel Man]

Looks like a dirk.

Only that I have the same one, but with my grandfather’s insurance company info on it…
