Lots of good suggestions here. Moras are hard to beat for light weifgt, and work better fot food prep than the CW would have you believe.
No one has mentioned one of my low-buck favorites, the Dexter-Russell Green River 5” fish knife, with a flat grind and a Kephart-ish feel.
Old Hickory now has a few smaller knives that come with leather sheaths. The first was the 6” belt knife mentioned above. It is still an outstanding bargain at around 22 bucks. There is a 4-incher that has styling cues of a poor man’s kephart, and a full flat grind, and a smaller one still that I have not had a look at.
