Rob Cosman's IBC Mortise Chisel: 7/16 inch
Determined to design a better mortise chisel, IBC and I teamed up and developed what I consider to be the best woodworking mortise chisel on the market today. These chisels meet all five criteria of a great mortise chisel: comfortable, high quality steel, sides square to the back (+/- .0015 of an inch accuracy), flat back, and the ability to change handles.
- Size: Mortise chisel handle length: 3.87 inches. Mortise chisel total length: approximately 9 inches. Mortise chisel blade length, including the tang is approximately 6 inches. Blade width: 7/16 inch, blade height: 1/2 inch.
Handle: Cherry handle is turned precisely on a lathe so they fit nicely to the ferrule and end cap and have a butter smooth surface. Shaped for a comfortable grip in the hand, they are finished with four coats of tung oil.
Steel: Made from AISI High Vanadium A2 tool which holds an edge beautifuy. Fully stress relieved, triple tempered, cryogenically treated and hardened to 60-62 HRC. Primary bevel is ground to 30°.
Flat Back. Each chisel is tested on a granite reference surface to ensure the back us flat to within .0005 of an inch.
Design: The blade tang extends through a hardened steel ferrule and into a threaded hardened steel core that is inserted through the center of the wood handle and is securely attached to an aluminum striking cap. This design allows you to easily replace the standard cherry handle with your own custom turned wood handle.
