Hidden tang vs. Full tang
I won't go into why a hidden tang is just as good as full tang (for most things) here, instead I'll link a video at the bottom you might want to watch if you're under the impression that hidden tangs aren't tough enough for hard use in the woods.
For those that don't know, a hidden tang (also called blind tang, rat tail tang, cut down tang etc) is a knife that has no part of the tang (the steel under the handle) visible. It's all encased in the handle material.
A full tang is a knife that has a visible tang (the steel under the handle) when viewed from the top or bottom and the handles are made up of two pieces of material, one on each side.
This will be mainly about the options that go along with a hidden tang, since there are many.
A hidden tang is made by drilling a hole through the handle material and then stacking that material onto the tang, capping it all off with a pommel of some sort. Most of my hidden tangs will be constructed something like this:
Notice that both knives have spacers near the guard, then a center section of longer handle material, then spacers and then the pommel. This is how I construct my hidden tangs. The spacers can be about anything, micarta, g10, stainless steel, brass etc. The same goes for the pommel. I can do about any material you'd like for it.
The guards are left long (like the top knife), mainly for looks. They don't hinder use unless you have a double guard and you use a knife by placing your thumb on the spine.
Here's a picture of what a double guard looks like. They're typically used on fighting/self defense knives.
Almost all models are available in a hidden tang. See the specific model description for price and availability of the option.
