I can’t tell if I’m sharpening incorrectly or if my file is just worn out. Is there a way to tell? I read somewhere to replace after like five sharpening a but that seems really short.

    Generally when sharpening a tooth that’s like 8 TPI (standard ripping saw) sharpening should need less than 8 strokes for each tooth.

    Also try soaking your file in vinegar overnight, they might be a lot better in the morning. It’s to do with chemical sharpening, the vinegar dissolves some metal around the files teeth and they get a bit sharper.
