Sword with blackened fittings
This two-handed sword features darkened guard, pommel and pommel-nut. In order to darken the fittings to a suitably dark tone to contrast with the brass elements, I used a thermal method.
The steel fittings were polished and cleaned thoroughly before being buried in a bed of coals and ash. The ash layer helps keep unwanted oxygen away from the metal as it heats up. For obvious reasons, no air is worked through the forge. As soon as the piece reaches a dark cherry red colour (judged in a dark room), it is briskly removed from the ash bed and all ash shaken of. A soft dry brush helps remove the odd patches of clinging ash.
After a few second of exposure to air, the piece is quenched in oil. Overheating or taking too long before quenching will lead to a layer that is too thick and flaky.
This method is only one of many used to blue or darken steel fittings.

Horse and gourd themed tsuba
Inspired by a series of recent unexpected events, I decided to work on this project. It refers to the sennin Chokwaro summoning a horse from his gourd and the expression 'as unexpected as a horse from a gourd.'
The pictures follow the project through the various stages.
The clay mixture used during the rust inducing process consists of finely ground red ochre and anthracite.

Tsuba project
Measuring, marking out and cutting.
Mounted in pitch-bowl for texturing and polishing. By heating it a few times in the forge, a natural surface texture is achieved. The scale will have to be dissolved afterwards to reveal the textured iron underneath. Now that the scale has been removed and the texture touched up in a few strategic spots, the rusting can commence. After a few weeks of building up the patina, it is stabilized in a hot tea bath.

Another front heavy dog's head (cutler's) hammer.
During this project I managed to weigh the piece during the various stages of production. The weight desired was 60 ounces.
This just illustrates how much steel is lost due to scaling during the forging process. For heavy forging not requiring forge-welding I use anthracite as is the case here. Forging with charcoal does consume less of your material. A 16.5cm length of 4.5cm diameter piece of axle steel was cut: 2114 g / 75 oz
After drifting and forging to shape, and including the weight of the plug removed from the eye: 1861 g / 65 oz
Grinding and filing: 1728 g / 61 oz
After polishing: 1703 g / 60 oz
The hammer head is 19cm long and 11.5cm measured from the face to where the eye starts. The face is 30mm square and heat treated.

Training equipment
A federschwert (training sword) and a painted steel buckler. The paint helps prevent rust on the buckler surface.
