Griptillian vs. Endura: it all comes down to personal preference, you really need to handle a knife before having a solid opinion about it. Comparatively the endura is thinner than the griptillian and boasts a blade of vg-10 or zdp-189 vs. the griptillians 154cm or 440c. Vg-10 and 154cm are very similar in performance, so similar in fact that I don't really know of any pro's or cons for one over the other. I own knives that utilize both steels. ZDP-189 however is a remarkable steel and outshines either when it comes to cutting performance, and the price point of the zdp-189 endura is in most cases lower than or the same price as the BM griptillian. Both the endura and the grip boast molded handles with stainless liners, and both have very dependable locking mechanisms. I have yet to have either an axis or a backlock fail. So there's my 2 cents.
