John Greco's 8670 based carbon steel knives, like the MST & 'Fighter", are well made and reasonably priced for custom pieces. The similar offerings of Fred Vollmer of Foley, AL are nice, too. Both have great sheaths - and Micarta or G10 handles. While hard, they are resharpenable with 'normal' tools. You can get an excellent custom 'military style' knife shipped to you for well less than $200 from either. A standard KaBar - at ~ $55 - is hard to beat, too, for so many applications. Heck, my pair of fixed Buck Vanguards, including the super S30V variant, will suffice for all of my needs. That is the key... my 'best' will be different from your's. Of course, that hasn't stopped me from acquiring the aforementioned examples, much less the Gerber S30V Freeman I think I want - and the new, aint out yet, S30v Buck kalinga Pro. Maybe I need a Gerber LMFII, too...
Who am I kidding? I had my Dad's WWII USN KaBar, his fellow veteran of the S. Pacific, when I was a young man - and into my college years. i still have it - and it has a few newer brothers. My use in the woods - hiking, for which it was overkill, and camping, for which it proved very effective - never left me wanting more.
As W.M. said, 'best' is so subjective... what are your real, or perceived, needs? Good luck!
