    Japanese hammers are different to Western hammers - not a claw in sight! This does not mean that are either superior or inferior, after all, they virtually do the same job. They are simply the Japanese approach, built upon hundreds of years of tool making tradition.

    Your Daruma Genno Hammer

    The Daruma Genno has a short fat steel head with large round faces. The handles are made from beautiful White Oak. The weight of these hammers means they are great for striking. Whether it is a chisel or a nail, this hammer has the weight for the task. Your hammer head has abundant surface area, so when you are striking, your hammer won’t miss even if you get lost in the moment. Also, one striking face is flat the other is slightly domed. Read on to learn more.

    Two weights

    The Daruma Genno hammers are available in two weights – 375g or 570g. These heads are drop forged. The lighter hammer is a popular choice for general chiselling and a particularly good choice for sculpture work where the hammer is used at different and constantly changing angles. The heavier hammer is an all-round pounder, perfect for nailing, driving wedges and mortising.

    Two striking faces

    One striking face is flat the other is slightly domed. The flat face can be used for a broad range of work in particular striking chisels. The domed face’s common purpose is to compress the surfaces of joints made from softer timbers before final fitting. “Killing” the joint by hammering allows for a very tight fit. The domed face is also excellent for the final setting of a nail.

    White Oak Handle

    The handles of the Daruma Genno are made from beautiful White Oak. The handles are smooth and feel great in the hand. Overall, these hammers are nicely balanced allowing for multiple grip positions depending on the work at hand. The solid steel hammer head absorbs the shock, so the striking force is not transferred to the handle. The hammer head are securely fitted using a timber wedge and steel wedge plug.


    Japanese hammers are a pleasure to use. With their compact heads and variety of designs, they are useful in all woodworking situations. If you are tapping in a fine wedge, adjusting a plane, chopping joints or nailing, there is a Japanese hammer for the task. Reality is that you will end up owning three, a kit tuned to the work you do.

    Japanese Chisels

    And let’s not forget Japanese Chisels. Most varieties of Japanese bench chisels are fitted with a steel hoop so they may be used with a steel hammer. This is different to the Western tradition of using a heavy wooden mallet. Using a steel hammer has distinct advantages, in particular the agility and preciseness one can achieve when working. From the tinniest tap to the heaviest blow, working with a steel head Japanese hammer provides you with incredible control.
