Japanese Electric Carving Tool Set. Professional. The cutting head of the "WOOD CARVER" reciprocates only when the cutting blade is being pressed to the work piece. The subtle change of the pressure against the work by your hands controls the speed and power of the reciprocation of the blade. And your hands are free from the trouble of adjusting a dial, switching or pressing control buttons. The high reciprocation speed capacity guarantees a smooth and professional cutting of any wood. HAVE A "WOOD CARVER", AND YOU HAVE THE HANDS OF A CRAFTSMAN. SAFE TO USE: A free-floating structure keeps the cutter motionless while the cutting blade is not pressed against the wood. Reciprocation stops as soon as the pressure on the blade is released. The best there is in this electric tool set.
