Actually, a "gut hook" as they're known now. I believe the original design of the hook in the old days was to retrieve a hot pot from the campfire. Now they are sharpened and used to unzip critters while field dressing.
I never had a like for these knives and never had a use for one. This was made by request for a client who is boar hunter and will definitely put it to good use.
