Ah, I hate to bring it up, but sometimes it just has too much to do with steel. Recent decisions by Gerber and CRKT to cut corners on steel quality have rendered many knife models less than desirable by many afficianados. Suddenly, even the borderline steels are now being offered with steels that no longer are borderline, but less. The result? Nice knives, lousy blades.
On the other hand, many others on this board seem to love Spyderco, which offers great blade quality, but smallish blade lengths. They also look a bit weird and the thumbholes look punched. Being a cheap bastard, I don't tend to buy C-bill knives. I reckon $40-65 is plenty generally.
The sudden demise of once-acceptable knives has, I think, created a mid-band section of knives that offer AUS 8 blades and are exceedingly good values. Made mostly by Cold Steel, CRKT, and a few others, these knives tend to be overlooked by many. The CRKT M21-14, for example, offers a fairly impressive chunk of stainless blade which is tough and has reasonably good edge retention. And they're easy to sharpen. They're every bit as good in tactical situations because of their excellent flipper mechanisms. Anyway, I think these are pretty much the unsung bargains of the knife world, especially since the low end knives are now probably not worth buying.
Benchmade has always been a great knife, too, but then they're hardly overlooked. Their assisted open knives get very good reviews and I'll probably end up buying one one of these days. But too many people underrate the AUS 8 knives, and that's unfortunate.
