Optima 

Fit into intricate joinery cuts when the others just won't. The blades are thin, and flat and have a concave edge profile that gets you into the tightest places with ease while the 65° skew angle of the blade shaves fibers cleanly. Whether you're tackling something as complicated as a full-blind dovetail or simple, but tiny tenons, Optima Skew Chisels will get the job done.
