Case 6380

First off it is of course a bone 6380 instead of a 8380 which would indicate pearl. The main blade is a 1976 4 dot blade but the handle looks newer with a tested shield that maybe came off of a case classic. Someone more knowledgable will be along soon. I have never seen a 70's knife with that color handle.

I fixed the mistake in the title. Yea the color of that bone is very strange.
