I'm looking for a medium sized fixed blade, mainly for home use. In my opinion, the Benchmade Nimravus looks much better and it seems well built although i hate those aluminium handles. However, 0160 and 0170 appears to be even sturdier. I don't like the design of both ZT fixed blades, but i'm more worried about the sheath button snap. It looks weak, so i need some opinions on it. So, which should i pick?
