Corner chisel

A corner chisel is a tool for cutting sharp internal corners in wood, often used for mortise joints or hinge rebates. The hole will typically be cut by a router, or occasionally drilled, leaving rounded corners. The function of the corner chisel is therefore similar to the square mortising chisel used on a mortising machine.
