Replacement blade for our No. 042 Medium Shoulder Plane. Comes with a 25° flat ground bevel.
The blade comes with a 25° flat ground bevel; it sits in the tool at 18°, making the included cutting angle 43°.
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

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.
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.
