The things I dislike is both of these are not very throw able, Dont throw these! If you want a throwing tomahawk, Cold Steel makes an awesome one. I would also put a lanyard on them, I am a bit paranoid and the SOG has a snap latch that opens down, if you weren't paying attention to your gear you could find it lost very easily and thats not cool! with the lanyard attached you wont worry about loosing it, but you lose the advantage of quick withdraw and deployment. you could add a quick detach somehow to make deployment quicker. I might find a good leather guy and have him make me a sheath that opens from the top. These are alot of fun and on the practical side, they can be used to cut small trees, light brush and vines. They both have a very sharp edge on them and with a little work it could be extremely sharp. So if you have been on the wall I say get one! Get it even just for fun!
