Paper slicing is a reasonable test, but you still have to make sure you’re getting rid of the burr. A burr will cut paper just fine but in actual use will dull very quickly. Having at least one finer grit and a strop makes this fairly easy. Doing it on one grit can be quite tricky.
+1 to not stressing about it though, half my knives have a patchwork look of different bevel angles along them from learning to sharpen. So long as the current bevel is consistent all the way to the apex they work just fine. Presumably a knife that is being sharpened is meant to be used and not admired for its looks.









I wouldn’t bother with this person, they’ve got a huge bee in their bonnet about bodybuilding and muscle mass. They seem to have extrapolated the negative health effects of doing huge amounts of steroids and putting on inhuman muscle mass out to all bodybuilding period, and they refuse to have this misconception educated out of them.
