This cast-iron chisel holder from Veritas converts a 1″ beveled edge chisel into a rabbet or shoulder plane. The 1-3/8″ wide by 5-1/2″ long by 2-1/2″ high chisel holder grips the chisel at a 45º angle with a solid brass thumbscrew. Once the chisel is properly seated, you can use it to clean up rabbets, tenons, and hinge recesses or cut 1″ wide grooves and dadoes up to 3/8″ deep.
Made in Canada, the Veritas chisel plane will run you $50 before shipping.
