I have a strong preference for Barlows, SAKs, and and a good 3 blade Stockman. I've carried a Stockman more than any other EDC knife. The 3 different blade profiles do almost anything I need. I've used them for cutting anything I have any business cutting with a folder, for carving wooden fishing lures, and field dressing small and large game.
I carry a Schrade Stockman everyday at work, along with a Gerber Multi Plier.
The stockman is one of the last US made Schrades, and I got it off Knives Live, or Saturday Night Gun/Knife Show. I forget which. It's identical to my 1978 Uncle Henry 897UH, except for having jigged bone scales, instead of the Staglon scales of the UH.
I use the ceramic tube from an industrial light bulb (metal halide or sodium, I forget) to keep it sharp.
I like the US military 4 blade knife, as made by Schrade, Camillus, and Ontario. The one with the stainless steel scales, a spear blade, screwdriver/bottle opener, can opener, and leather punch.
For a fixed blade, an HI Bonecutter suits my needs, as does a USMC Ka-Bar.
