The Buck 102 Woodsman is a great smaller knife. The Buck 692 Vanguard, admittedly $55 through the mail, is excellent, too, although it has a 4.1" blade - great grip. That version has a rubber grip and Kydex sheath - $5-$10 more gets the 192 with laminated rosewood grip and a leather sheath - a beaut. Both have a great feel.
Another great choice, with rubber 'Safe-T-Grips' and great carbon steel blades are the Marbles 'Fieldcraft' and 'Trailcraft' knives - <$41 shipped from KSF (Old stock - current 'Safe-T-Grip' Marbles are SS and made 'overseas'.). The best fb buy under $50 is still the Buck 119 Special, admiitedly a 6", but ~$34 at Wally World. You can watch Les Stroud carry one on several of the latter Canadian 'Survivorman' series. Everything I have suggested is made in the USA.
