I've been looking at the Wilson Cop Tool any thoughts on this blade carry option.
Why not the Boker cop tool? For under $50, if you're interested, give it a try.
But as to design, it seems to be a Razel homage with a hook added. I don't like serrated blades, as they're hard to sharpen, but they increase blade size, and stay sharp longer than non-serrated.
Look at the Graham Brothers Razel, or the CRKT versions. I like the ringed versions, as I can let go of the knife to do something, and have it hanging from my pinkie finger ready to swing back into use.
