If you have ever chopped out waste in softer woods (Pine, Cedar, Aspen, Poplar, etc) then you have felt the frustration of the wood fibers collapsing and tearing out in big chunks with typical bench chisels ground at 25-30 degrees. I fixed this problem by grinding a more acute bevel on an IBC chisel specifically for chopping out waste in softer woods.

Chop waste in soft woods without chunks tearing out.
17 degree primary bevel cleanly slices through soft wood fibers.
Available in custom turned cherry handle.

Product Details:

Size: Bench chisel handle length: approximately 3.9 inches. Bench chisel total length: approximately 9 inches. Bench chisel blade length, including the tang is approximately 6 inches. Blade width: 1/4 inch.

Handle: Cherry handle is turned precisely on a lathe so it fits nicely to the ferrule and the end cap and have a butter smooth surface. Shaped for a comfortable grip in the hand, they are finished with three coats of 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 17°.
Flat Back. Each chisel is tested on a granite reference surface to ensure the back is 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

1/4 in IBC chisel 17 degree

After receiving honing and polishing the blade, I tested on 3/4 in pine stock. I made 1/16 in cut across the end grain both tangentially and radially. The chisel made clean cuts each time. I am not finished honing the blade. I can only expect the results to get even better. My standard 25 degree bench chisel did not perform nearly as well - tear outs were noticed. bottom line - I'm pleased. thanks rob klh

Great chisel!

This really helps out when doing dovetails in softer wood. Keeps that tear out to a minimum wirh that 17° bevel. When you sharpen it using Rob's method, you have a very highly efficient tool.

Excellent, Cuts pine nice and lean,

Great Tool

Fits like a glove

17 deg is really needed

It took longer than expected to prepare the back. But once done, it worked quite well doing dovetails in white pine. I had been using LN and Blue Spruce (regular bevel) chisels. They cut in about 1/32 inch from the surface and then crumbled the wood. The 17 degree chisels (1/4 and 1/2”) cut deeper and took fine shavings cleanly. HOWEVER, the aluminum cap on the IBC chisels leaves dark marks and dents in my Blue Spruce mallet, which is resin-impregnated figured maple. So if I do a lot of work that needs 17 deg chisels, I’ll get some more LN chisels and grind them to 17 degrees. Too bad IBC doesn’t make mortise chisels. Their handle design wood be good for that application.
