I have one in the rotation. Sometimes the smaller size(than most of my EDC's), having a double edge and is rugged/cheap is what I am looking for to carry rather than more traditional boot knives. Easy to sharpen and I don't care if it gets thrashed unlike my other boot knives which are mostly for self protection roles. Dry hands I have no problem but I am sure any liquid/sweat etc would change that, I have seen on the forum here people doing various things to improve that. The only real downside in some circumstances is legality and other people's perception of its intended use.
This a favorite of mine(I really like push knives)and you really can get a firm grip.
