Rob Cosman's IBC Half-Blind Chisel: 5/8 inch
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 5/8 inch bevel edge chisels with custom fit cherry handles.
- Has a 13/16 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.
Half blind chisel
It is a lot lighter in weight than I expected. I didn't find it as good as expected for cleaning out blind dovetail corners compared to using a narrow straight chisel which being smaller can generate more force to cut with.
