Wiley does the SE conversions; good price and quality.
Have you or anyone here that is well known here on BF ever had any blades done by them? Because like I said earlier I want to talk to someone that has dealt with them first hand before I go putting one in the mail to them or recommending them to anyone I know. IF they are an honest, reputable company that does high quality work I might just give them a try. I would love to have one of those older G-10 handled, C-60 Spyderco Ayoob models done in SE.
I also remember some of the Forum guys at one time talking about a guy named VEFF I think it was. But I think that guy may have just sold serrated sharpening tools if my memory is right. But I also heard good things about the guy named VEFF too.
