... the knives on those "test" videos do break in the blade area ... however most of the times this happens is due to the fact that the point that actually breaks is the exact fulcrum of where the blade is being levered ... Of course it's going to give in the area where the most pressure is being applied ...common physics
Yup, like I said, it stands to reason. I just flipped through nearly all of
those videos again (not the only source for knife destruction, but the most popular), and there are 18 stick-tang or push-tang knives out of 38 total. Of the 18, the Mora and Glock are not full tang. Of those 18, the HI khukuri, M9 bayonet, Buck Nighthawk, and S&W knives broke at the tang before in the blade, and the SOG Seal2000 breaks at the ricasso but only after significant blade loss (edge).
... the thinnest part of the entire part of the knife is the actual blade. On most stick tang models, this is not the case..
It is the case, the blade is nearly always thinner than the tang due to grinding, and keep in mind that most stress endured by a knife is lateral stress on the cutting edge itself, meaning a large chip or fracture in the blade is the most common cause of failure - simple physics, like you said. Think about how thin the tang on a broad sword is compared to the broad blade... but then think about how thin the blade is ground compared to the tang and also what part of the weapon/tool endures the most stress and variety of force vectors.
.. any stick tang knives such as the M9 bayonet, the kukuri, or any of the 3 Ka-bar models, they all do actually break in the tang area for one reason or another.
Out of 18 models, 4 break in the tang before the blade. For those that break in the tang (or ricasso anyway)
at all, it's usually because noss is hammering on the handle with the ricasso in the vise in a deliberate effort to get that tang to snap (not always easy). *shrug* I think that evidence is sufficient to lay the argument to rest, don't you? Anyone else have questions or concerns about stick-tang knives .. or swords, for that matter?
(btw, not trying to be an ass about this, just trying to promote truth in the face of common misconceptions that lack substantive evidence.)
I don't know what else to say, all of these knives are solid knives, and I still would use a stick tang, but if my life were on the line and I could only take one, it would most certainly be a full tang model.
For me, it's really a toss-up between my Cattaraugus 225Q and my Swamp Rat RMD. I'd probably take the RMD based on versatility of the design (love that choil), but in a colder environment I'd take the push-tang Catt to keep the metal off my hands.
By the way, BOTH are "full tang" - the "full" means that the tang travels the entire
length of the handle, it has nothing to do with any other dimension (another common misconception). Think about full-length tapered or hollow (skeletonized) tangs, or any knife where the blade is wider than the tang at any point...
Happy Thanksgiving!
