I've just ordered a Shibata Kotetsu AS gyuto 210mm, it's coming on Monday. I'll admit my sharpening skills are pretty rubbish, I've never got any good/consistent results. I think this is due to shaky hands. I own: Naniwa Gouken Hayabusa 4000 Kitayama 8000 Spyderco sharpmaker + ultra fine rods I've also just ordered a King 250/1000 which I am going to use and start from scratch with some beater knives I own. I only ever get decent result from the spyderco, but it's still not quite as sharp as I would like. I've tried stropping on newspaper, but this seems to make no difference. I might have a leather belt (it might be fake leather) lying around that I can try. My question is as follows: Am I going to improve the edge on my new Kotetsu if I take it to the Kitayama 8000, or is there a big risk of messing up the OOTB edge if I don't know what I'm doing? How many passes should I be doing, should I just be maintaining the existing edge, should I put on a microbevel, what things should I look out for etc? I am aiming to replicate this: Any help or advice would be greatly appreciated.
