Bump!
I was a beautiful fall day, the temperature hovering around 80°F. I was sitting on the deck, working on correcting the edge on a particularly hard steel chef's knife (≈61 Rockwell). I've been working on this knife off and on for two weeks. It's a stunning Japanese piece and I prefer to true-up its edge carefully, slowly, by hand.
My knife sharpening stones were all soaking as I thought that I'd also touch-up some kitchen knives.
Marcia brought me one of her favorite knives, saying that it isn't as sharp as she remembered it to be. A quick look proved her to be correct. I doubt that she could cut herself with it. She might make a bruise.
The edge was so nicked that it looked like a saw.
Here it is, sitting on a 320-grit whetstone that I was using on the Japanese knife. 320-grit is a coarse stone for ≈57 Rockwell Chicago Cutlery carbon steel. It cuts that stuff pretty darn fast. But after several minutes I could see that headway was slow. *
Then I remembered that I have a Ken Onion Work Sharp Knife Sharpener in a basement cabinet. Two passes with a coarse belt and the knife edge was clean and amazingly sharp. Finer belts polished the edge and Marcia had a super sharp knife to, once more, abuse. I was so happy about that I ran all of her knives through the Ken Onion Work Sharp Sharpener. It only takes a few minutes and they have a better edge that 99% of the kitchen knives.
I think it's a good investment for someone's moderately priced kitchen, pocket and hunting knives. If you buy high-end knives—maybe not the best choice.
* I made a mistake, here. What looked like nicks may have been only serious edge turns. I might have been able to put the rolled edges back into position had I first burnished the knife on a smooth butcher's steel with a lot of pressure. But, without considering that, I ground away the rolled edge on the coarse stone, leaving what appeared to be a serious nick or chip.
