I'm curious, other than in TV/movies/Jujutsu training...... where on earth is it considered a good idea to carry any sharp edged weapon on the belt and edge exposed?
Regardless of the head design, it seems incredibly stupid to carry any tomahawk or fixed blade knife with the edge unprotected.
Ouch. "Incredibly stupid" seems a bit harsh. With the right design, I've carried tomahawks and hatchets in my belt with no problems whatsoever. Poorly designed models have left scratches or nicked clothing. When I carry it, I don't want to have to go through 5 steps to get to it (if I need heavy work, I'll have an axe or hatchet ... often with no cover either). The 'hawk is for utility work, but also, for me, another self-defense item. I know it's there, I work around it and don't have a problem ... after many, many years of using them.
Nothing wrong if you
want to carry a cover on yours. Also, I'm not sure just how one would carry a fixed blade knife without a sheath, but I didn't mention fixed blades, so I don't know how they even came up in this conversation.
I'd imagine the tomahawks or other sharp-edged weapons in TVs and Movies are not sharp, and aren't, for the most part, real. But I am not in the movies and I don't know how they do things. Insofar as training, just as in most weapon training, the majority of work is done with wooden or blunted tomahawks because, hey, we're serious, not crazy.
It's frankly amazing how well they work for techniques other than cutting/slicing/hacking, and I'm going to assume you were not comparing serious training to the fantasy world of TV and Movies.
Anyway, if for
your purposes, you want a cover on yours then by all means, it's a free country (in most places) so have at it! I have no trouble with your choice and won't even sink to pejoratives. You do you, I'll do me, and we can both be happy in our own little worlds.
