Hi, I was working in the shop today with another woodworker friend and he noticed that I burnish my card scraper a lot. I burnish all 4 sides every 7 or 8 minutes while I use it. I have a Two Cherries scraper and I think maybe the steel may be softer than his or something.
I use the scraper until I can no longer feel the edge catching (at which point I get more dust than small shavings). I then switch sides or burnish.
How often does everyone else burnish their card scrapers?
