The improved smoothing plane is ECE’s crown jewel. It will create super-thin shavings on even the most difficult woods. It features an adjustable mouth, an ironwood sole, the primus adjustment mechanism, close-fitting cap iron, and a varnished cherry body. The “Primus” iron adjustment mechanism is all metal and excellently machined. Simply turn the adjusting knob clockwise for a thicker shaving and counter-clockwise for thinner. There is no backlash or slop in the system due to a large spring in the heel which keeps tension against the adjuster. The Ironwood soles glides over your work better than any metal plane can. 48mm (1 7/8″) Iron, 50 degree cutting angle, 225mm (8 7/8″) body length. Made in Germany.
