Large Scraping Plane Blade

Replacement blade for our No. 112 Large Scraping Plane. A2 Tool Steel hardened to Rockwell 60-62, cryogenically treated and double tempered. Our heat treating technique ensures that the blade will take and hold a very fine edge for a long time. After heat treating, the blade is fully surface ground on the top, back, and cutting edge, giving a smooth, flat surface that will take a mirror finish very quickly.

  • 2-7/8" wide
  • .140" thick
  • A2 Tool Steel

Geometry:

The blade comes with a 45° flat ground bevel; the blade angle can be adjusted in the tool from 75° to 100°.

Sharpening:

Our Scraping Plane comes with a much thicker blade than the original. This allows the blade to be prepared differently than other scrapers. We have found that our Scraping Plane blades sharpen easily and produce a better surface with a 45° bevel, honed to a sharp edge like a plane blade. Honing a secondary bevel of 5° will help achieve a razor edge quickly. We do not recommend using a burr, at least until you get used to using the tool. Slightly rounding the corners of the blade with a stone will prevent them from marking the work.

Note: In order to sharpen the No. 112 blade in our Honing Guide, the Brass thumbscrew needs to be removed. The thumbscrew is reverse threaded, and held with non-permanent Loctite. To remove, insert one screwdriver into the thumbscrew and a second into the end of the threaded rod, then turn clock-wise. If needed, heat may used to help break the Loctite bond.

For more information on advanced sharpening we recommend David Charlesworth’s video Plane Sharpening, available in both DVD and streaming formats.

Burnishing:

If you wish to create a burr, hone the blade, then hold upright in a vise. Using a burnisher, begin by holding the burnisher at about 45° to the blade, working up to 75°. Work the edge until you can feel a distinct ‘hook’ all the way across. Be very careful not to cut yourself on the upright blade.

Materials:

Made from A2 Tool Steel hardened to Rockwell 60-62, cryogenically treated and double tempered. Our heat treating technique ensures that the blade will take and hold a very fine edge for a long time. After heat treating, the blade is fully surface ground on the top, back, and cutting edge, giving a smooth, flat surface that will take a mirror finish very quickly.

Maintenance:

Blades should be kept lightly oiled or waxed to prevent rust. We recommend Jojoba Oil, a plant based oil product that is non-toxic, odor-free and easy to use. Also, in our shop, we use a fine abrasive handblock to remove any light surface oxide from tool bodies and blades. Jojoba Oil and abrasive handblocks are available from us.
