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.

Product Details:

  • 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: 3/8 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. 

  • Made in Canada

Excellent + a call from Rob...

As always, tool is Rob's IBC-branded tools are great. And, it's always nice to get a phone call from Rob saying, "your item is on the way." As it's shipped from Canada with an expected delivery of two weeks the mortise chisel arrived much earlier than expected. Cool!

IBC Mortise Chisel

I have never done a mortise and tenon joint before, so I have been practicing with this chisel and it is such a pleasure to use. I have aways to go before I use a mortise and tenon joint on a project but it is my lack of skill right now not the tool that is the issue. I will be buying a few other of the IBC mortise chisels from Rob for sure. It is the right size weight and balance, it just feels solid.

Oh baby this thing can chop

Haven't gotten an opportunity to chop some 3/8" mortises with it yet, but it's been my go-to chisel for a few weeks and I'm loving the heft even for non-mortise stuff.

3/8" mortise chisel

I have not sharpened yet, but I keep handling it, like a toy. Really like the feel of it. As soon as my my shop is put back together I will be putting an edge to it. But I like it as well as my lie nelson bench chisels. Thanks Rob and all of all the people that put this order together.
