For use in our No. 49 Tongue & Groove Plane. Centers on 1/2" stock, leaving a .166" wide tongue and .230" deep grooves. On narrower or wider boards, the tongue will be offset from center, but still hidden within the joint.
Note: Blade does not work in vintage Stanley planes.
The blade comes with a 25° flat ground bevel; it sits in the tool at 45°, bevel down.
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

The blade is O1 Tool Steel, hardened to Rockwell 60-62.
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.
