To quote STR: "[T]he tip up vs tip down carry pocket clip is another [difference]. The blade shape on the 710 is unlike any of the Sebenzas really when you actually compare them side to side and the blade steel of course is different also. The stand off count is higher in the 710 than the Sebenza and, number of lock cuts, blade shape at the tang for the lock contact and stop differences, detent ball size difference , slab material thickness difference and, one being stainless the other titanium, weight differences and perhaps most importantly 'size difference', meaning the actual foot print, length, width, thickness etc etc in the pocket and in the hand.

But, even if the sanrenmu was identical in all dimensions, after having handled a seb., there is really not a competion & CR hasn't lost a sale to Sanrenmu. Its like the difference between a poster of a painting and an actual painting, at least for me.
