The little dagger is a Korium Pic, made in Japan. It was my dad's and he had it his special drawer that I could only look in when he was around. I think he got it at a souvenir shop sometime after WWII. Possibly, his younger brother bought it for him somewhere. (Uncle Billy was a USAF Lifer). The other one I just bought off Craig's list for $20. He advertised it as 1916-1919. I think it was from the '60s, but it looks like it lived in the sheath for a long time. It's Imperial, Prov., RI. I'm not too concerned about the Imperial, but just wondered about the Korium PIC. Both sheaths need re-stitched due to dry-rotting.
