A marking knife earns its keep by the line it leaves. This one is ground from hardened high-carbon 1095 tool steel and finished with a double-bevel spear point, so it tracks a straightedge cleanly and scores an even wall on both faces of a cut — exactly what dovetail layout asks for. The fine point reaches into tight corners and registers against a pin or tail without crushing the fibres. A crisp knife line is the difference between a joint that closes and one that gaps. Made in Canada.

IBC Chisels Are Premier Tools

The tool's design, materials, and machining are first rate. These chisels feel like they belong in your hand and, after a proper sharpening, perform exactly as you would expect at this price point. Are they expensive? Yes, but they're heirloom tools.

Excellent tool

I started a cabinet project using hickory and have not had to sharpen my chisel over the entire project. It was still cutting butt hinge mortices right up to the end and still grabs a fingernail. Thoroughly pleased.

Best chisel I have ever held

You can tell great care and thought went into its design and craftsmanship. The balance is great, it disassembles and comes back together like clockwork. The blade is superb, with clean, crisp edges.

Amazing

Putting a secondary and tertiary bevel was a breeze, and the way it cuts is beyond comparison. End grain on sapele, walnut, and maple come off the plane in beautiful solid ribbons.

As promised!

Easy to sharpen, well made and a high degree of pride of ownership. It is a tool you stand back and say I don't know how you can improve on this. Buy it once and never regret it.

Highly recommended

This quality one fits like a glove. I see $150 for a chisel as nearly free, lucky to have these for so little investment.
