I've never believed in that "you have to own this knife" buzz. If it doesn't suit your budget or needs, then no, you don't.
The ability for just about anyone that can run CAD and afford a Haas machine can start making mid-tech titanium knives now.
What makes one knife better than the other? Materials? Couldn't be, as most of these companies use Titanium and S35VN. While S35VN is a great steel, you can get very high quality knives in Titanium in M4, M390, etc for less, sometimes far less (ZT, WE, Rike, Reate, etc). Once you get to the point where you are paying $500 for a knife, you aren't buying it because it's a superior knife, but either for exclusivity, to be part of "the club" or maybe an appreciation for the engineering and/or the design. Let's be honest, a $80 Cold Steel or $200 ZT can do everything a that a $500 XM18, SnG or Sebenza does, and sometimes better.
All that being said, these designs are known and copied for a reason, whether it's the detail to precision (CRK), being a "tough guy" (XM/SnG), a major design innovation (Ti Frame Lock, Flipper, durability to weight ratio, etc).. they have all give reason for all the attention. If these guys want to stay at the top, they need to do it with customer service and quality, because the market is filled with competition.
For me, I do care for CRK's. I love the precision behind the knife and the overall classic and simplistic nature of the knife. Hinderer knives have never really done anything for me, especially since ZT has arrived. Striders, not sure.. I'd like to check one out but have never pulled the trigger.
Thanks just my take, not that it's right, just my perspective.
