Got some left-over inner spools from work. 5" diameter and roughly 1/2" densely packedcardboard walls. Could not slice completely thru but let go with all I had in a vertical-downward strike. Can't remember exactly how much penetration 2" or 3". These spools are about 3 ft. long and designed to support 100 pounds or so. The Ontario kat had very little damage to edge, still sharp also: 1095 carbon steel. also the blade itself did not have any noticeable warp. But the KC ninja-to: 5160 carbon spring steel lost much of the edge and warped vertically similar to a kukhri angle. Not as much. roughly 1/2" along the spine. also bent laterally 1/2" or so. Bent the lateral edge straight, a benefit of differential hardening. I think the ninja-to is hardened that way, not really sure though.Mainly carry a big blade while hiking in AZ an whack at brush etc. Much more fun than a machete! But overall I'm more impressed with the Ontario stuff. Plain, simple full-tang. All that's required is an additional wrap on the handle. I like that strider knives wrap alot. Drawback to Otario is there is no tsuba(guard) on the blade but it really fits well in their kydex sheath and multiple carry options,etc. The KC stuff has a traditional saya but who wears traditional clothing and who wants a sheath sticking out as your romping thru the woods!
