The problem when routing a hinge or lock plate recess is that it always leaves you with rounded corners. You could square off the corners with a normal chisel, however, the AUKTools Corner Chisel is a fast and accurate way to sort those unfinished corners out. Get clean, square and professional-looking corners every time.

The blade is HSS 10mm square and sharpened to a perfect 90-degree 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.

The overall size (25mm x 25mm x 70mm) is compact enough to carry in your pocket, take with you in any toolbox, or store on any shelf.
