No. 4 or 5 Bench Plane Roughing Blade

Our 2" Cambered Blade is intended for roughing projects with the No. 4 or No. 5 Bench Planes.

  • 8" Radius
  • A2 steel
  • 2" wide x .125" thick.

Geometry:

The blade is flat ground with a 25° bevel.

Blade Sharpening:

The blade comes ready to use, but honing a secondary bevel of 5° or 10° will increase performance, help achieve a razor edge quickly, and improve edge life in hardwoods. You can find sharpening instructions in a printable PDF format here:

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

Materials:

Made from A2 Tool Steel, cryogenically treated, hardened to Rockwell 60-62 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.
