This is the Tojiro 150 mm petty that I purchased along with the 210 mm gyuto. I decided to go with a slightly different handle configuration using the same woods. The saya is constructed of Poplar and painted with black milk paint.
Milk paint is made using milk protein, lime and earth or mineral pigments. It is environmentally friendly and non-toxic. It has been used for hundreds of years on furniture and in the past families typically had their own recipe they would pass down through the generations. It is water based so it doesn’t just form a layer on top of the surface that can chip off. It gets into the pores of the wood more like a stain than modern paints.
