Thanks Pete! More fodder for us to educate the customers on not putting even stainless steel knives in the dishwasher

wow yes I have experienced the pits on a damacus knife aswell, and I wondered where the hell did they come from? I was sure it was some manufacturer defect, thanks for bringing this up.

I think the pitting occurs on areas that have micro-chipping. You're seeing the knife in person and I'm not so you've got a better view, but VG-10 is fairly "stainless". Unless the knife is being bleached or run through the machine regularly I can't imagine it corroding to that degree. At any rate, Spyderco does a lot of VG-10 and I've never seen it corrode like that. Interesting!

Agree I try and get all my customers to not use the dishwasher it's the enemy of high quality knives. On Western style knives it destroys the rivets and the handles. I also notice on Shuns like the one you have there it hurts the mirror finish. They get a cloudy haze on them. It can be re-polished but that takes a lot of time on the buffing wheel.

How would you sharpen the same knife without using any electric equipment?

these are obviously chips. why would huge "pits" form only on the very edge of a blade...? a blade would have to be under salt water for centuries to form pits this massive, and they'd be all over the surface.
