Ulster Knife Co "factory error" knife.
This is an interesting "factory error" knife. I always try to emphasize that after WWII, Imperial, Scharde, and Ulster were all under the same corporate umbrella, so any of the (then three) factories could produce knives with any of the trademarks/stamps that were owned by the coproration. This knife has the HAMMER BRAND USA tang stamp (Imperial) with an ULSTER KNIFE CO blade etch.
