The Accu-Burr AB2 is a big sibling to the very popular Accu-Burr Burnisher. The AB2 is ¼” in diameter, 4 inches long and works on scraper blades up to 4mm (5/32”) thick. (The original Accu-Burr AB1 3/16” diameter rod works on scraper blades from 0.010" up to 0.100" thick.)
The Accu-Burr features a rod with 3 V-shaped grooves around its middle. The grooves are precision-ground to turn a fine, medium or coarse burr simultaneously on both sides of any prepared scraper edge. This enables you to form a precise and repeatable burr simultaneously on both edges of the scraper. The Accu-Burr is extremely versatile, working on any shape scraper and on virtually any hardness (including HSS steel blades at approximately Rc 65). You’ll also get no deflection on thin card scrapers, or profile scrapers that are necessarily held high above the vise.
To use, hold the Accu-Burr perpendicular to the scraper edge and centered on one of the three groove options - fine (5°), medium (10°) or coarse (15°). Draw the Accu-Burr firmly along the length of the scraper edge with a firm downward force. Use a tiny amount of oil for smoothness of operation. The burnishing action will raise a very slight burr. If you cannot feel any burr, repeat as needed. The Accu-Burr can also be used as a conventional burnisher by drawing its ungrooved section along the scraper’s edge.

I really love the Accu-Burr. It’s not every day a new tool comes out that challenges the tried-and-true methods (well... for some people) and comes out ahead. It has certainly
been a game changer for my finish prep. - Ethan Sincox (the Kilted Woodworker), Quercus Magazine, Nov/Dec 2022
