B&S Mobile Sharpening sharpened all of our knives and I must say I didn't know you could get them that sharp. They where on time, friendly and did a great job. I read the negative comment on this page so I asked the guy what would happen if he damaged a knife and he said he would replace it but that it would be highly unlikely to happen. I told him about the other comment and he said it was the opposition being nasty.........
