I recently picked up an old bone handled gunstock jack made for Sears, and I'm trying to figure out which company made this knife and around when it was made. It is etched on the master blade "Craftsman 9465 Sta-sharp" and tang stamped "Highcarbon steel U.S.A." Sorry I can't post pics, but we are still using a film camera. Has anyone collecting the gunstock jack pattern run across one of these? Does anyone have any idea about how to figure out the contractor? I'm guessing Camillus or Schrade but I haven't seen what their versions of this pattern looked like. Thanks for the help.
