A few months ago, my wife left part of a 150 Heiji SS petty wet and it got a rust spot. I fixed it and sharpened it but it scared her enough she decided to stick with stainless (Suisin, Ashi, Masahiro pettys). A couple of days ago, she decided to pick up the Heiji petty again. When I got home from work, she made it a point to tell me that she used it and "It was a revelation." Heiji SS rocks. Just thought I'd share.
