The ZT 0550 is sort of similar because it's a titanium frame lock with G10 on the other side. It's fairly thick though and heavy maybe that's what you mean by "Hard use".
A Spyderco PM2 is sort of the same because it's a nice, light, thin, well engineered piece. I'm not a huge fan of the lock, some are, I have so many other frame/liner locks that the compression lock is just awkward.
The Benchmade 755 MPR is a small, brick like, little knife. It's similar construction as the Striders with the wrap around G10. It's got a shorter blade but I'll be cutting edge isn't that much different. I sold mine, kind of wish I hadn't now but I never used it.
The SNG is unique it looks pretty beefy yet it's very light and thin. It's pretty much perfect for me.
I also had an Adamas that I sold. I'm not a fan of the Axis lock but I really liked the knife. It does seem a little slow I guess especially compared to the 0550 that open like an auto. The Adamas does have a good feel to it though especially considering how thick it was (.7" if I recall), it's nicely contoured and a good looking knife.
