The square head genno has rounded corners for strength, narrows slightly at the waist and is noted for its excellent directional stability. Ideal for assembly work, knocking in pegs and nails and also makes a very acceptable choice for driving Japanese chisels and setting Japanese planes.
The polished faces are selectively hardened by quenching the head under a stream of flowing water, this gives durable working surfaces but leaves the middle of the head softer, which deadens the blow and kills vibration. The polished hachimaki bands around the faces are not a laminated layer but a traditional decorative touch that tidies up the appearance after polishing the faces.
Available in a range of weights to suit lighter or heavier tasks, for chisel work the 375g (13.2oz) size is recommended.
