The Japanese ingot forging hammers primary function is forging down ingots into usable billets. They are made to Ford Hallam's specs with a traditional Osage orange handle to help promote recoil, absorb harmful vibrations, to help save your joints. Each hammer head is roughly 650 grams and 5" long

There are 3 hammers:

A cross pien hammer - This hammer is for the first step in breaking down the ingot, and will move the metal the fastest. It can also be used as a raising hammer.

A square faced forming hammer - This is the second hammer to use in forging the ingot. With a pillowed face, it will smooth the deep marks left by the cross pien. It can also be used in various forging and forming tasks.

A planishing hammer - This is the final hammer used in forging the ingot into a usable billet. It has a flat round face that will smooth and flatten the ingot into a finished billet, that is ready for abrasives or layout. This hammer can also be used for various planishing operations, and as a light weight bladesmithing hammer.
