I just bought a Large and Mini Griptillian and I have to return them both! The blade centering was so bad it interfered with the opening and closing of the knife (the Large was really bad). Has anyone else had a similar problem? 2 out of 2 is a pretty bad failure rate. I really liked the Mini (except for the blade centering), but now I'm concerned about the quality, and whether or not I should buy another one, or spend my money elsewhere?
