The handle on the MK II is cast. You could find a welder qualified to weld them back on and grind them smooth. If you still have the pieces? This can be done by very skilled welders. I have seen cast aluminum and other cast parts on cars welded back together before. BTW what the heck were you doing with that knife buddy? Huuuhhhh Urrrrrrrunch!
Definition:
A 'tang' is the protrusion of the steel into the handle of a knife or tool.
The knife tang can be either full tang, meaning that it extends into the full length of the handle, or partial tang, extending only part way into the handle as a socket or file end.
The tang extension into the handle not only provides a way of attaching the handle, but improves the weight and balance of the knife, and adds strength and durability.
quillon (or quillion)
In the very old days, this term referred to the arms or extensions in a crossguard that protruded farthest from the axis of the sword or dagger. In modern knives, this also refers to the projections that keep the hand from sliding forward onto the cutting edge, or backward off the knife handle. So a modern knife may have a front quillon or quillons, and rear quillon or quillons. The use of this word has been adapted to modern knives probably for lack of a better term to define those protuberances. By the way, the word is properly pronounced: "key-on." I frequently violate pronunciation, in an effort to be a rude westerner... even though it seems the word has evolved from the quill of a bird's feather, so one would think you would pronounce it like that, but the word is French. Does that mean that the French of old wrote with key pens and birds have keys at the base of their feathers? Ah, yes... er... we-we.
Bumping this back up to the top...
Still looking for someone to fix this blade...
I'll check with a Couple of the Welders up here in my Area...
I had not even thought of doing that...
