A highly accurate and versatile, Shoulder and Chisel plane in one. The sides are precision ground, 90 degrees to the sole. It's one of the more comfortable shoulder planes to use.
You can micro-adjust the 3/4" blade for a precise depth of cut.
When you need to trim and clean up tenons, rabbets, and other woodworking joints for a perfect fit, there really isn't a better tool for the job. Trim a few thousandths away at a time to sneak up on that perfect fit. The top will slide forward and back to open and close the mouth. It also comes off, turning it into a Chisel Plane. The blade is high carbon steel, hardened, and tempered to HRC 63.
