I'm been looking at getting my first custom folder. I've been looking at R.J. Martin, Rick Hinderer, and Yuna. I would really like something other than S30V. Almost all the Yuna folders are ZDP/ATS-34 which I think would make a great blade. However, I also like the fact that R.J. Martin uses ball bearings instead of Bronze washers. What are some other good custom manufacturers and what do you guys think of the three I listed?
