I have an extrema ratio panther that I got in trade a while back. If you google it you can find a little info on it. From what I can figure out it was produced in very small numbers and only distributed locally (in Italy). It was designed for some kind of spec ops Italian unit. It was never sold in the US as far as I can tell and I've never seen one for sale. It doesn't have a pocket clip I was told it came from ER like that but it has holes drilled in the g10 for a clip so I'm sure if you call them they'll send you a clip for free just might take a week of shipping. It has a rope/seatbelt cutter, glass breaker razor sharp double edge serrated on top plain on underside. If you look close at the handle the "jimping" or whatever it's called is all the way up the front and the back. It is very secure in the hand. I need a gun safe so I gotta lose a few. Like I said I don't really know what to ask for it. How about 500 as a start. Would consider partial trades for a nice strider thanks
