Yo Kosta: I’m just an old man that doesn’t know too much. I watch little how-to videos to learn something. With minimal practice, sharpening a card scraper is about as simple a process as it comes. If you want to learn how to sharpen a card scraper watch the link below.

Todd – do you really want to encourage (ggg). Mangle comes to mind. Hey, I learned how to sharpen a card from your video but couldn’t find it on my favorites. So I googled. Maybe you could post it again.

kosta,
have you looked into forming a rolled edge with a burnisher? there are a million ways to sharpen a card scraper and everyone has different degrees of success with each, but I noticed you didn’t mentioned this method and thought you might be interested. karson blogged it a long time ago. the more arrows in your quiver, the easier it is to hit your mark.

I’ll second davidroberts linked video – good one. explains the need to have a 90 degree edge, honing it, and the burnishing of the burr to get shavings.

IMNSHO, Using a card scraper without a burr is like using a rock instead of a hammer.

i like todds method of card scraper sharpening. no need to burnish the edge at all. simply a few strokes across the file at 90° and you are done

There is a big difference between setting up a card scraper for scrapping versus shaving.

A blunt edge scrapes.
A burred edge shaves.

Both are useful and are tradeoffs at opposite ends of the skills spectrum.
IMNSHO, There is value in knowing the difference and appreciating both techniques.
I use and teach both methods. More importantly, I teach how they are different and when to use each.
