What is nice about the Toothpick is they come in different sizes from 3" to 5". I have a large and a mini.
Most slim line trappers (Utility) are 4 1/4" with narrow blades
Canal Street produce a 3 3/4" Half Moon Trapper in 14-4 CrMo, which is very slim in the pocket and with a wider blade, and the steel is excellent.
The scales can be from jigged bone to stag or elk.
The jigged bone can be quite reasonably priced, look around
A fine knife.
($50+)
Queen produces a 3 5/8" Copperhead in D2, also available in a linerlock (Folding Hunter).
A good solid slim knife, not as fine as the Canal 1/2 Moon.
I like it.
($45+)
There is the Queen Swing Guard, which is a fancy slipjoint with a lockback.
Case calls them Cheetas
I do not have these knives..
Queen Tear Drop jack with a linerlock
Queen Mountain Men, you then jump into much more hefty knives at 4 1/2" with or without a lockback
Schatt and Morgan has Cotton Samplers in different sizes, steels, and prices
