I have Japanese kitchen cutlery that I've been sharpening the old school way--800/6000 grit Japanese stones. I can make them razor sharp, but obviously, that takes a while. I'm wondering if a tool like the Work Sharp WSKTS-KO with fine belts will do delicate enough work to not prematurely wear out my good knives? I know it'll sharpen them well but I'm concerned about excess metal removal. Thoughts from those who have or have used the machine are appreciated.
