Support BladeForums! Paid memberships don't see ads! I don't have that many knives, but the ones I do have, which include full liners, are all skeletonized. The 710, the 810, the 575, both 580s... I haven't done research beyond my own collection and maybe ones I've handled in stores, but this is the only one that I know of which is NOT skeletonized. Wouldn't you want to save a bit of weight where possible? The first time I looked at mine, I thought maybe it was a manufacturing defect, but looking at some other disassembly videos and reviews, I see that this is just how they are. Why is that?
