Reminds me of a time we sent out some chisels to be touched up. It was a commercial woodworking tools store that had a guy who did sharpening outsourced. They were really old chisels that would need a fair bit of grinding to get back to a point where they could be hand-sharpened. We get them back, and it was a total disaster. They took off like a half inch of steel, chisels were coarsely ground, very crudely hollowed, and blued from the heat.

Moral: don't trust anybody to work on your tools unless you know they do good work. There's a lot of amateurs out there.
