FOX Chiroptera Karambit Folding Knife

are there fast ways to open this? description says wave but yeah there is not one.

Thinking the same thing. I have a Derespina also with no wave...which is too bad. Closed, this has an excellent strike point, tho. Still a nice karambit - I'm working on a wave add on to replace the thumb studs. Got a wire arrangement on the Derespina that works - just looks like $!+.
