I'll list what I'd buy in four different "classes":
Folder: REKAT Sifu, the finest combat folder made today bar none. Only the Ryan Biohazard even comes close and that's questionable even though it's triple the price.
Small fixed blade: Bud Nealy makes good stuff, he kinda specializes in this category. The new SOG Recondo is pretty cool too. A lot of New Yorkers buy 4" fixed blades because they can conceal 'em, Bob Dozier and Bud and several others do good work in that size range. What really matters in this class is grip design, specifically one that doesn't allow your hand to slide up the blade on a hard stab. That and sheath design. "Balance" isn't such a factor with the little critters.
Big "lightweight fixed": the Hossom is indeed a damn fine piece. I don't like the lack of lower guard but other than that it ain't at all bad. The Ontario Bagwells are also excellent, the steel isn't as good but it's plenty for a fight..they're the best production-grade big Bowies made. Last, Ernie Meyer at Black Cloud knows how to make big, properly balanced fighting Bowies in the sub-$500 range for handmades.
"Big Bopper": if you get tired of finess and wanna just cleave something from eyebrow to a**hole
, go buy a Khukuri. Specifically something in the 17" to 21" overall (grip included) range and a "lightweight" (by Khuk standards) blade style like a Chaimpuri or Sirupati. Go talk to Bill Martino at HI, one of the forums here. Nothing does as much damage as quickly as these beasts
. Speaking seriously, these are excellent handmade fighting knives worthy of consideration, and a really good buy.
