Definition of Tang: A projecting shank, prong, fang, or tongue that connects the blade with the handle



Full Tang
The term full tang means that the knife/sword is one solid piece and the 2 handle pieces are pinned on to the blade, one on each side. This is the strongest of the tang types. Half tang knives go the length of the knife handle, but only half the width of it.

Push Tang
This is a partial tang that is pushed into and secured to the handle with glue or epoxy. They usually come in full and half push- half only going into half of the handle, while full being pushed in the full length of the handle.

Rat Tail Tang
In a rat tail tang, the tang narrows as it goes through the handle and is either threaded at the end or is welded to a piece of threaded rod. A bolt or threaded pommel secures the blade to the handle.
