Tired of fighting to get a clean burr on your card scraper?

This is my take on the Accu-Burr—a shop-made burnisher I call the Scraper Spine Bender.
Built from hardened O1 tool steel, it’s got a single angled V-groove that forms a burr fast, without all the slipping, guessing, or hand cramps.

In this full build, I walk through:

* Filing the groove angle by hand
* Heat treating O1 tool steel
* Building the handles from spalted curly maple
* Testing it on tough hardwood (ash) to show it actually works
* If you’ve ever struggled to get a consistent edge on a scraper—or wondered what makes tools like the Accu-Burr work—this build breaks it all down.
