Even being careful not to round off the tips, I did round off a few of mine. I use 10" arkansas stones, from soft all the way through translucent. It really doesn't take much time, but when I want a true mirror finish, and the sharpest edges I have ever seen, I use my KME system. It is an awesome sharpener, that most anyone can use, and the owner of the company is amazing. He will talk to you on the phone and really work with you so that anyone can use it correctly and have excellent results. I never use my work sharp anymore unless it's on a machete or hatchet. BB
