Making a Bamboo Scoop for Water Forging

Simple technology for pouring water on the anvil, takeno mizusashi (竹の水差し) made from a piece of bamboo.

Forging with a thin film of water on the anvil and hammer prevents forge scale or oxide from being hammered into the surface of the steel. The hot steel instantly vaporizes the water and the resulting steam explosion blows the scale off of the work, keeping it clean as it is worked. This type of bamboo scoop is a traditional style tool for evenly applying water to the surface of the anvil or the hot steel. Read more about the process of making one.

Making Fire with Bamboo – museum forge first lighting

The first night turned out to be quite an event as there were three forges and six blacksmiths/strikers operating in the museum workshop. Thanks to Tim of Reforged Ironworks, and Josh for their energy and charcoal chopping to get the forge up and running, and their assistance swinging the big sledges to finish drifting and shaping the smaller hand hammers as the first preparatory projects in the charcoal forge.

Making 篩 for charcoal screening

Traditional Japanese swordsmithing forges are fueled by softwood charcoal which is first chopped, screened, and sorted into several sizes for different stages of the forging process. The “furui” (篩) or sieve is used to separate different sizes of charcoal during the sumi-kiri process. This one is the smallest mesh of the four, made from window screen, and saves the fines for the charcoal bed and allows the powder to fall through. See the whole museum forge project here.

Testing Scrap Steel for Knife Making

Most of history was forged with steel that had no designated number or specified ingredient list. Historical smiths would interpret the quality and properties of steel based solely on careful observation and simple testing procedures. To this day, Japanese swordsmiths work exclusively with unnumbered steel made with charcoal… Continue reading
