The Big Horn 19566 Shoulder Plane is the ideal woodworking tool for trimming tenons, corners, rabbits, and other joinery projects. Its adjustable mouth allows for fine or coarse shavings by sliding the upper section forward or backward. Plus, you can convert it into a chisel plane by removing the upper section, perfect for easy access to tight corners. The 3/4” blade ensures clean corners without leaving ridges. Precision-ground and polished flat, both the sole and the back of the blade guarantee optimal performance.
