I simply don't understand why some people like certain knife features, for example Emerson Waves, concave blades (a pain for me to sharpen), Tanto blades in a folder, etc. But that's cool, I just stay away from them, as long as there is a market and users, why not ?
Along these lines is the recent LW and liner-less craze: except for saving manufacturing costs, why it would be good for moving parts of a knife to sit in G10 only ? For me, a moving steel Pivot needs to be ankered in Steel or Titanium. Why have an HRC > 60 blade and Pivot and then anker the Pivot in plastic ? Minimal liners as in the Manix LW show that proper ankering can be done without much weight impact. And regarding weight, in my pocket (I don't use clips), anything lighter than ~120g "disappears" anyways.
Just because a folder has steel liners, it doesn't have to be a "pry-bar". My CF Military, with steel liners, comes in at 117g, similar to - say - the Native Chief.
So I don't understand liner-less and LW. But that''s cool, you guys enjoy. The only downside for me is, that I can't enjoy some knife shapes and steels (for example, a liner'ed M4 Native 5 would be great). On the other hand, whoever bought Native Chief or M4 Native 5 might also have bought them if Spyderco had included minimal liners (such as in the Manix 2 LW).
I guess it's a business trade-off: how much additional money do you have to spend in manufacturing, to be inclusive of the few knife loving engineers like me ?
