That's an 0456. It's a chonk. I'm pretty sure it's plus of 6 oz. despite having a relatively compact profile. I
really like the blade design. That modified Wharnie shape is right up my alley. I like the design and it is really comfy in-hand - but I think some internal milling would have gone a long way in making it feel a bit more balanced for its size. The finish work is choice.
Also - don't see that Rexford 0808 on the right (
crufflers
) get mentioned much, but I love that blade and the grip ergos. IMO, one of the best blade profiles ZT has ever released for an EDC. I wish ZT would do more blade designs like this. Same thing though - could use a little de-chonking to make it more balanced - that back spacer is like an anchor.
