I does look very usefull. I just can't get past my visions of slicing my hand off with it after engaging the release lever on accident. Also not sure about the durability since it is on a rotator pin rather than having a true full or even half tang. Due to the tang issues it's really only as strong as a folding knife rather than a fixed blade and there are a few different knife/saw combo locking folding knives on the market that are more compact and with which I am probably less likely to lose fingers.
