I've had one custom knife, a Track made in Whitefish, Montana about 1972. I designed the knife and they made it, pretty much a plain drop point. They like'd it so well they added it to their line. Later Jon Sundra did an article on it in shooting times magazine. It was the production knife, not mine. Mine has a rosewood handle and brass butt cap and that front piece, don't remember what its called. Finger guard!
Now I use an old Schrade, Uncle Henry or my pocket knife (Old Timer) mostly. But I found a Buck folder that I like well and a friend bought me a Buck sheath knife I really like (drop point w/4" blade. Brass butt cap and finger guard, no model on the knife). I also have a Browning mod 816 that my ex-wife bought me and a very old Carl Schlieber made in Germany. The most favorite knife I ever had was a Puma Hunters Pal, that was a great knife. But don't want to pay that much for a knife anymore. Bottom line, when I'm hunting you'll find me with a couple Schrades of one kind or another.
