If you have ever cut a half-blind dovetail then you know how challenging cleaning out the pin socket is, especially in the corners.  Not happy with the skew and fishtail chisels available, I designed and made my own half-blind chisel and they work great!

  • These chisels are made from our Rob Cosman IBC 3/8 inch bevel edge chisels with custom fit cherry handles. 

  • Has a 7/16 inch cutting depth.
  • Dovetail-shape makes accessing the back corners of the half-blind socket easy.

  • Sides of the chisel tip are angled to easily fit into the corners of the half-blind socket.

  • One chisel does both corners verses a left and right set of skew chisels.

  • Pushing through endgrain is tough; unlike skew chisels, our half-blind chisels keeps your line of force straight making it easier to push through the endgrain.

  • My students love them!  Try it once and you will never want to cut half-blind dovetails without it.

Perfect!

After sharpening these, I’ve got nothing but praise for these two chisels. They provide the perfect means of cleaning out the pins in blind dovetails. Glad I purchased them.

Half blind chisel

The chisel performed perfectly. Tool’s back was flat needed little effort to polish the back. The handle is very comfortable. Overall excellent chisel.

Half-Blind Chisel

Nice sharp edge but I’m disappointed in the quality of the walnut and finish. I was expecting nice dark heartwood but see mostly light sapwood. Appears to be very little finish on it as well. I’ll probably end up replacing it with much better walnut.

Half-Blind Chisels

I got a 3/8” and it sure makes cleaning out a dovetail easier than a standard whistle. I will probably get a 5/8” later on.
