I just registered and have a question - I don't know if I'm even in the right place, but .....I bought a Brad Southard Flipper and it came sharp but after a bit I had to touch up the edge. I have NEVER had such a hard time sharpening a blade, and I've been doing it for hundreds of years. I thought, and read, that CTS204P was a super steel - better than S30V - but the edge roll was worse than cheap Chinese steel !!! Did I buy a clone ?? After checking with all the souses available I do not believe it was ( notice "was" ) a clone. I could put a good edge on it (it was always toothy, though) and after very moderate use it would barely slice through paper. A little stropping brought the edge back OK. Does anybody have any ideas why ?
