What fleam angle did you settle on for that Disston, 15 degrees or more like 20? I freehand with a triangular file too but my teeth drift once I get past the first inch.

Buddy's mower guy did the same thing, took months to grow back.

My buddy does cabinet installs down in Tucson and had the same thing bite him. Lady called him back 4 months later, said her forks smelled like paint thinner. He pulled the drawer and the bottom was still tacky from the finish, plus a pile of sanding dust stuck to it. Cost him a whole Saturday and a new set of flatware to make it right, which was way more than a roll of liner woulda run him.
