The jointer plane is a plane up to one meter long with a turning chisel, a handle and sometimes a horn. It serves to plan perfectly smooth long pieces already worked with the jack plane. Sometimes one or two cross poles are attached on or in the block in order to be able to work in pairs: one craftsman pushes, another pulls. Sometimes a rope is tied to the front crossbar.
Because this plane has to do fine work, the angle of the chisel is quite large and the space for the cut is small. The latter is completely straight, only the corners are rounded so as not to leave any traces. [MOT]
