(e.g., bird’s-eye maple) it’s handy to have a back bevelled blade at hand. Changing blades has the same effect as using a high-pitch plane.
We recommend a back bevel of 15° to 20° for most diffi cult planing situations, which yields a cutting angle from 60° to 65°. Note that even within this range, there is a signifi cant difference in how the plane performs. At 60°, the plane will cut well against the grain, except around knots and the more dramatic grain swirls. Increasing the angle to 65° will all but eliminate tear-out, even around knots and rippled grain
such as found in bird’s-eye or curly maple. The 5° increase will, however, make the plane noticeably more diffi cult to push. We therefore recommend beginning with a 15° back bevel to produce a 60° cutting angle, and only increase it by another 5° to 65° if you still experience tear-out. It is also important not to skew the plane in use when a back bevel is employed as described here as this has the effect of
