Routing a hinge or lock plate recess always leaves you with rounded corners. You could square off the corners with a normal chisel. However, the UJK Corner chisel is much quicker and highly accurate. Clean, perfectly square corners give the job a professional, clean looking finish.

The blade is tungsten steel, sharpened to a perfect 90° corner. The steel body has locating lugs, which automatically align the chisel. A sharp tap with a hammer and the spring loaded chisel cleanly cuts the corner. Pare away the little piece of waste for a perfect cut every time.
