This plane was designed for bass bar fitting, though it works well for many applications. The idea was to allow the index finger to get close to the surface to give a better feel for the tilt of the plane. The lip at the tip gives a positive point to push against. The low angle of the blade minimizes the forward force that must be applied. It is a true 30° front surface approach angle. This is unlike some "low-angle" block planes in which the blade is mounted at 12° but the bevel is on top, so the actual front surface approach angle is 42°.
The body is made of machined pieces of brass that have been soldered together. The blade is 1/2" wide, A2 steel with a Rockwell hardness of 61.
