Yup. HD has done many posting on how he does it. I pretty much do it the same way, just with a different sander. Same concept though.

I was worried about screwing stuff up as well. I had a couple of Cold Steel Bushman's lying around. They are very, very inexpensive and I figured I wouldn't cry if I messed those up. So, I practiced on those. That was enough for me to feel confident grinding my better knives.

I wish I knew how to sharpen this way years ago!
