If you wan't your knives to have burn marks all the way up the edge, please choose this service! He is 72, and his prices haven't changed in 20 years, you will pay for what you get! I have about 30 knives, all that were ruined by him, all of them have burn marks up one side where they were sharpened, the other side was never sharpened.......use him as a last resort, there are much better out there!
