How do you know when saw files need to be replaced?
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.
Easiest way to tell would be to pick up a new file and try it. If it works, then you needed a new file. If it doesnt, then you need to work on your technique.
