I am a part time bladesmith (husband and father of 3 children ages 6 and under) practicing in many areas of steel creation. I am a bladesmith, but i am also an adept in iron smelting with smelt master Mark Green. 6 years of smelting iron ore we have mined into iron or steel. Some 80 full smelts under my belt. Most product goes to my good friend for his traditional sword production, but i have earned quite a bit for jacket material in future sanmai. I am also adept in the process of steel making most commonly used by Japanese Swordsmiths called Orishigane. The remelting of clean iron or low carbon steel into ultra high carbon steel that must be wrought to homogenize carbon content and remove impurities from the steel. I make steels in the 1.3-1.9% C range. I have been working this type of steel into plates and then billets for future nihonto inspired blades and even kitchen knives. This steel processed and used in my sanmai has lead to beautiful results (jnat stone polish). And peering down my metallurgical microscope, checking the weld line (I sanmai orishigane to W2, turning that into a core billet and then sandwiched that further between 1018 mild) the top being W2 and below, lighter color is orishigane (with silica slags present from the traditional folding with rice straw ash and mud slurry as Japanese swordsmiths do. The micrographs revealed the 9 folded orishigane to be between .8 and .9% Carbon (It started around 1.5-1.7) Kitchen knives using sanmai construction is my main study. I have spent years learning traditional steel making methods, but have also spent several years practicing the craft of sanmai construction using low carbon jacket material under my powerhammer that has been set up to mimic the shops and spring hammers you see being used in Japan. I have also been working in the area of crucible steel, watering steel, wootz, etc...I approach it unique to many, using a singular source of feed material to get desired carbon content (my orishigane only). This has lead to much success.
