Interesting. I've never had a S&W knife and then again I own the original knife made for S&W by Track Knives in Whitefish, Mont. Had it made about 1972. Then a couple years later I saw a very similar S&W model that Jon Sundra wrote up on. I checked with Track and sure enough, S&W did contract for some of them but to my knowledge my was the only one with a bone handle. Great knife, I designed it. My son has that knife now.
