This thread I thought would be interesting to a lot of people getting into making blades with hamon, also for more experienced people to give tips and advice, as I am not an expert and am still learning.
Here is the first step I take when claying the blade (Tsuchioki) I use a few different blends of clay this particular one is a mixture of refractory clay, stone, and for the thinner solution added charcoal to a watered down clay mixture.
I place the thicker clay on the spine and the watered down clay along the edge to speed up the quench transformation.
I will be using straight rain water for my quench fluid, heated up until it is hot to the touch and lightly steaming.
This will be quenched at dull / cherry red, and then traditional yaki modoshi tempering will take place, using the water drop test until it dances on the blade. All of my heat treatment will be gauged by colour change alone, and temps tested with traditional non digital methods.
Enjoy.
