Greetings, everybody. I am trying to find information on a fixed blade Imperial knife that was in my grandfathers tackle box. My grandfather passed in 1972. Several years ago I received his tackle box, and this knife was in it. It is approx 7" tip to butt, black plastic handle, no guard, and no serrations on the back of the blade. Ive found tang stamp information for Imperial knives online, but not for this knife, which is stamped with the word Imperial in cursive and nothing more. I would love to know more about this knife. Any information would be greatly appreciated. THANK YOU!
