I bought one of these when they first came out. It was really a neat little knife.

I personaly liked the beefy recurve on the knife blade. I wish more small folders had wide blades like this instead of the narrow Warncliff style.
The Paul lock was pretty facinating. Once you got the hang of it, you could open and close it pretty fast-one handed. Not as efficient as an Axis though, because you had to adjust your grip a little once it was open. Still, it was one of those mechanisms that was really addictive.
This was a really handsome little knife. The button lock was totaly cool and unique.
After about a week of practice opening/closing, the blade developed play, both side to side as well as up and down. Not very much mind you, but it was there. I had never even cut anything with it. It didn't look like there was a way to tighten the Paul Axial lock. I think it is a fixed system.
I have heard about quality control issues with Lone Wolf, maybe this was the problem. Maybe the Paul Axial design is flawed. Maybe I got a bad one. I don't know. There were a couple other guys on this forum that said they had similar problems with the Paul Axial system, they didn't have the Ritter model though.
SO,
I returned it. :grumpy:
Too bad. I have other Ritters and they have been great knives. Of course Benchmade makes them. I hope Doug doesn't get burned on this one because he has some good design ideas. The vendor for Ritter knives is top notch too.
I haven't heard any other feedback from othe Mk4 owners so maybe they're good knives. Let us know if you get one.
