Okay, enough clowning around. In my opinion, this is the Lum Chinese that Spyderco should have made first. It is a serious working tool. The G-10 has enough texture to eliminate the slippery feel of the anodized aluminum on the original, the larger size provides enough handle for a variety of grips and the extra leverage for cutting harder materials. If the original was a hit, this one deserves to be a bases loaded grand slam home run.
The Walker liner lock? It's fine with me, but I've always thought that if you need a lock, you're using the wrong tool. Stick with fixed blades.
