Knife is sharp piece with a handle on it. If it'll do what it's needed for, it's good enough. For many, a three buck box cutter will serve their needs better than a $300 Sebenza. Others just need something that will ride on a key chain to open packages, cut string, strip wires, and the like. Price is no indication of usefulness.
For a couple of years, my EDC carry was a Gerber LST the NRA gave me for renewing my membership. You get no cheaper than free, and I dressed out a couple of deer with it because I had it on me. The knife you have on you is always better than the knife you don't. Carried a no-name $2 all stainless special for a bunch of years, and it did everything I needed it to do. Got slippery dressing out deer, but I had it on me, and it got the job done.
Run into my share of junk, too. The dollar Barlowes that were so common in country stores 50 years ago could be counted on to have their scales fall off in under a year, but I had the same thing happen with two Gerbers, which were high buck knives c. 1970. I paid about $25 each for those, and you can multiple by six to adjust for inflation.
I've been following this thread with interest, and, time after time, the advocates of very expensive knives have admitted they can't explain it, and fallen back on "You just have to experience it." I've been using knives well over 50 years, and they cut or they don't. They fit my hand or they don't. They take an edge and hold it or they don't. They fall apart or they don't.
Price does not seem to have a lot to do with it.
