Frank,
It seems that you (like me) are contemplaing buying a Carny. I have an axis (p.p. 730s) and really like it. I'm a lefty, but I've been told that it's not too much of a problem. I think I'm going to have to pick one up so I can find out which I like better.
BTW, IMHO, I don't think that the average user will ever take either axis or rolling locks to failure. I know that if there is positive pressure on the blade, it is not likely to close...leaving negative or side pressure to fear. With the axis, if there is negative pressure, the tang exerts a fricting force on the lockbar, which prevents it from accutaing back. The axis seems pretty safe to me.
I'd like to hear from more Carny owners. Already read through all the posts, and am convinced I should get one. I wonder if anyone can convince me to NOT get one???That would be quite a challenge.
