This doesn't seem like a thread that has the potential for edification, but I'll try my diplomatic best.
Innovation's a funny thing - usually the market will dictate the level required. Some examples:
For folks like us who demand constant innovation, the Spyderco's & Benchmades are the brands for us. They alter their product line often with new designs, collaborations, steels, scale materials, locks, etc., and we keep buying.
For other collectors, maybe all they want to collect is every possible 3 inch Case stockman - Red bone, Yellow bone, stag, brown jigged, etc., etc., and they will keep buying the same 3 inch Stockman (a 100 or more yr. old design) with the different handle. Other than the one-handed "Russ-Lock", I don't think Case has put out a new design in 20 years - yet they have no problem maintaining their market superiority with folks who like that kind of product.
How about SAK's ? Pretty unchanged for 50 years.
Buck? Schrade? Gerber? Cammillus?
These more "traditional" makers have all put out "innovative" designs in the last few years, with varying success. Part of the reason might be snobs like us who think "If I want a pen knife for Grandpa, I'll get a Buck. If I want a cool new toy for me, I'll get a (tactical maker)".
My Dad would much rather have a Buck 110 than any of my newfangled Zytel, ATS-xx folders. He would also rather walk than drive a front-wheel drive car, and there's an example of the market closing in on him as tastes have changed.
Diff'rent strokes, I guess.
