I only have a few fixed blade knives. Nothing even remotely considered "high end", but all are serviceable:

Cold Steel SRK and Recon Tanto (the Tanto is too long, the SRK is quite nice IMHO)
Buck <something_or_other> (I forgot it's model number - about a 4" blade)
Becker Necker (not comfortable in the hand - too short, too thin - good for a backup or a minimalist lightweight knife though)
Frosts Mora Clipper (several of these - I prefer the carbon over the stainless)

Of my meager collection of fixed blades the one I use the most, by far, is the least inexpensive of the bunch - the Mora. That is the "go to" knife around our house for the whole family. I also carry another one while hiking, and so does my daughter. IMHO you really don't need more than the Mora, unless you want to play lumberjack and split 8" diameter logs by hammering your knife into them. If you want easy replacements, you just can't get any better than buying half a dozen Moras for the same price as one of the other knifes you are looking at, and having all those spare Moras sitting around the house.
