Are you looking for full titanium? Or can the non locking scale be something different? A bunch of ZT knives should fit the bill.
Also, what size do you like? If you like them in the large range, the Reate Horizon D with either full titanium or a carbon fiber show side scale is a really nice knife in addition to the already mentioned and smaller Wave.
I really wish there were a bunch of similar knives but with a different lock type and something other than a frame lock. I've had too many nice knives close on me unexpectedly which is a failure in my book. They also have to be adjusted and made just right to flip nicely and reliably. By far the best flipper I own is a Kershaw RAM that uses a HAWK lock and spring pressure to hold the blade closed and provide the resistance to a flipper instead of a ball and detent. I have 4 of them and they all flip reliably, effortlessly, and consistently and better than any frame lock I own or have tried.
I really wish the new Benchmade 781 Anthem had a flipper. I'm sure it could be done with a little ingenuity and now that it looks like the AXIS lock patent has really expired I really hope some other companies put their spin on it and it becomes popular like the frame lock which started gaining popularity with makers when the patent expired.
