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.

Making a Swordsmith Anvil from Scrap

A Japanese swordsmith style anvil made from junkyard scrap. The two side pieces are cast steel or iron John Deere 8255C rear counterweights from a shovel dozer. They weigh about 200-240lbs each and measure about 2 1/8″ x 14 3/4″ x 25″. There is a ‘T’ shaped face and stem that extends to the ground between the plates made from welded spring or tool steel and weighs about 70lbs.

The face is about 1 3/8″ x 6″ x 15 1/4″ and has a pritchel hole in it and a sharp edge for cutting on one corner. The combined weight of the plates bolted onto the face and stem should be between 475 and 520lbs. The finished anvil should sit 7-7.5 sun from the ground or from the seat height.

Inside look at a traditional kaiken mounting

A look inside the carving of a small kaiken tanto mounting (futokoro-gatana) with additional examples from an Edo period tsuka and an even older shirasaya.

The omote is the “public side” of a tanto or sword, the side that faces outwards both when being worn and when on display. The edge faces upwards and the handle is on the left when displaying nihonto. The ura is the “private side” and faces away from the viewer when on display and towards the body when worn.

Satetsu – testing iron sand, skimboarding bladesmith

Collecting and testing some local iron sand (magnetite/hematite) at the beach using a harddrive magnet. These samples were collected as west coast additions to soulsmith Pierre Nadeau’s satetsu archive. Bonus summer skimboard footage thanks to a couple of good friends who stopped by to enjoy the beach. Additional footage thanks to Dan King and Crow~san, watch Dan’s skimboard edit here: https://youtu.be/udAXDnRkfYI?t=2m54s
