I do not understand why anyone would attach a knife to their leg or arm. It just seems like it could not be easy to get to when you need to get to it. I put mine on my belt and wear it in the center covering my belly button and lower unit. Easy to get to with either hand and not in the way. Just saying...
I have one on my belt and one on my leg. I got caught up once and simultaneously dropped a knife. I now have two. Inside of right leg is good for me.
Isn't it hard to sit down with the knife in front?
I tried making the sleeve out of an old wetsuit to make a knife holder, but it wasn't stretchy enough and wouldn't stay in place. It kept wanting to ride down. I still want a knife on the top of the thigh or on the chest, mounted to a vest. I might do that with some binding clips, now that I think about it.
