Thank's for all your comment! Alan, I try to use google translate too...
Joshua we have many furnaces (crucible steel, wootz, bloom, little, big...) I can make photo of process and furnaces when we use it if you want! I try to found information to do very little bloom (1kg) and to do crucible steel but in bar shapped (to work with only hand tools, and alone).
Today I have finish a blade... Full hamered surface and just metal brush to polish. After this treatment, one hour in hot vinegar. The wood chisels is to make the japanese style handle, i try a new geometry so the handle is'nt finish. I think it's too large to work precisely (1cm). The newt will be around 0,5cm.
The glue used is knife cement. (rosin of pine (collected in nature), brick and oil). It's removable with hot water and very very strong!
