The Patent Pending Accu-Burr ™ Carbide Burnisher is a game changer when it comes to turning precise, consistent, and effective hooks (or burrs) on cabinet scrapers.  No burnisher will produce better results with less effort and less skill. Guaranteed. This completely new type of burnisher is a collaboration of Blackburn Tools, Union Manufacturing and Lakeshore Carbide.

The heart of the Accu-Burr™ is a 3/16" diameter carbide rod with three precision shaped V-grooves of slightly differing angles (5°, 10°, and 15°) ground in the center of the rod. These grooves create burrs on both sides of any scraper edge in a single pass.  The 5° groove makes fine hooks for refining finishes or when working with thin venerers, the 10° groove (most common) makes medium hooks for everyday use and the 15° groove makes heavy hooks for shaping wood or removing finishes.

 The Accu-Burr™ will turn a precise and consistent hook on:

  • any imaginable size and shape card scraper, it can turn burrs in concave profiles as tight as 3/32” radius
  • any thickness card scraper from as thin as 0.010” up to 0.100” thick
  • any hardness scraper, even High-Speed Steel versions with a hardness of RC 65
  • thin and profiled scrapers that are held high in a vise that would normally deflect and pose difficulties with a traditional rod burnisher

How to use:

Prepare your scraper by filing and honing the edges and faces. Secure your scraper in a vise. Hold your Accu-Burr™ carbide burnisher perpendicular to the scraper edge and centered on either the fine, medium, or coarse groove (the deepest groove is for the coarse burr). Applying light even downward pressure on the burnisher, draw it firmly and smoothly along the length of the prepared scraper edge (a drop of oil on the burnisher will make this action even smoother). The Accu-Burr ™ is self-centering and will draw out a burr on both sides in a single motion. This burnishing will raise a burr that can be barely felt with your finger; if no burr is felt, repeat as needed, but with increasing force, until a nearly imperceptible burr is formed along the entire length of the scraper. A burr can be refreshed 2-3 times by taking an additional pass or two with the Accu-Burr ™ before the edge will need to be refiled and rehoned. 

 Two version of the Accu-Burr ™ are available:  a 3” long unhandled (rod alone) or the “Junior” with two solid brass handles with an overall length of 5-1/4”. The unhandled rod can be used alone, but the Junior handled version does provide some additional leverage. You can make you own handles by adding 3/16” compression fittings (available separately) to both ends of the rod. You can make your own wooden handles using Union Manufacturing solid brass ferrules (available separately).

Or you can add cost effective handles using 3/16" brass brake line compression fittings (available separately). 

AB2 Information:

The traditional method for preparing a scraper plane blade involved filing and honing a 45-degree edge on the blade, followed by forming a hook or burr on this bevel at a 30-degree angle. Achieving the perfect burr was a tricky process and typically required a dedicated burnisher or jig. For generations, this approach was believed to produce the best scraper edge for achieving the finest surface finish. The Accu-Burr AB2 changes this paradigm by enabling users to create a burr on both edges of a square-edged scraper blade, suitable for use with popular scraper plane models like the Stanley #12, #112, and the ever-popular #80.

The AB2 is constructed from the same carbide material and possesses the same geometry as the AB1, with grooves at 5, 10, and 15 degrees. However, it has a larger diameter (1/4” instead of 3/16”) and a longer length (4” instead of 3”). The AB2 is designed to accommodate scrapers up to 5/32” thick, while the AB1 is intended for scrapers up to 0.100”.

While the AB1 rod is relatively small and may be challenging to handle, it performs optimally when equipped with handles. In contrast, the AB2 is more substantial in size and possesses sufficient mass to operate effectively, even without handles.
