The answers to your questions are going to be as varied as the knife buyer's individual tastes. I think
trends change over time as new technologies, materials and techniques develop. From traditional knives
to lockbacks to axis locks and frame locks, from inferior metals to super steels and leather pouches to
felt lined kydex sheaths.
I don't mind lock bar stabelizers but I also think that steel inserts on the lockbar un-necessary. My oldest
Ti framelock hasn't moved a bit, nor has it developed any late lockup due to not having a steel insert.
I don't think every fixed blade needs a sawback. One is fine, but if I'm near the house I'm using a real saw.
I don't think all OTF's from a certain manufacturer need to have glass breakers on the end. I understand maybe
certain users want it available, but all knives of a particular model shouldn't have to suffer their existence.
I think that the idea that a knife should have to pass a test that is unrelated to it's intended use is silly. My
knife doesn't need to pass heavy spinewhack tests any more than it needs to go through a metal detector or
act as a throwing knife.
Some guys don't mind sharpening a knife frequently or how rust resistant their knife is, so the question of
flavor of the month steels is also viable.
