The threaded tang, threaded only top and bottom, should avoid repeating the failure of the original kabar design, which (I believe) had complete threading of a very reduced diameter, failures of which led to the crosspin....which also can break at the hole, or the reduced shoulder of tang upon which the pommel rests...as with any normal knife. Even the normally peened bayonet pommel can break at the shoulder if pommel used hard enough.

The current Army version of the venerable JPK called the ASEK, uses the exact same pommel arrangement as the Chimera original posted knife, and had no problems passing trials.

The same blade as the Chimera in the cheaper SP-6 has a ferrule hole through a round ended tang, and could break there, except nobody pounds or hammers much with the lightweight plastic handle.

To get to the roundabout point/tang/pommel of the story, anything can break if you beat on it enough. If you need a sledge to break large amounts cinder block, go get one. Not one of the knives/bayonets mentioned are going to hold up indefinitely when doing so, otherwise.











apologies about the sizes of several images, they certainly seemed large enough when saving.
