I believe the "paring knife" has a long history of being carred in a sheath made of a cereal or tissue box and tape or glue.
I like the "old timey" 3.5 inch carbon steel Old Hickory and Russell Green River/Dexter Russell paring knives with rivited wood scales. They make a great low cost "Bird and Trout" knife (and patch knife) in my opinion.
They are good for much more than just mere KP duty, at any rate.
Back in the 1960's and very early 1970's when I was BSA, some in the troop carried just such a knife and sheath on the camping trips.

(Not I. I had a Ontario 499 "Jet Pilot Survival Knife")
I think I need to get another one ... The Old Hickory probably, for the signature "forging marks" on the blade, and some glue and wax to make a proper waxed paper/cardboard sheath from a tissue box.

I doubt I'll be going to my camper anytime soon to get my paring knife or anything else.
