I mix two different steels, for example one pure carbon steel with 1% carbon and one carbon/nickel steel with 1% carbon and 2 % nickel. I forge weld these two and draw the steel by forging to double lengths, folding the piece in the middle and forge welding again. This procedure gets repeated until the amount of desired layers are achieved, let’s say 120- 140 layers. After this, when the piece is approximately 1inch thick (25mm) 1½inches wide (35mm) and 10inches long (25cm), it is time to do some drilling or grinding into the piece. This will show off like nice waves or pools when the steel is finished. By drilling or grinding one third into the piece on each side and then heating it up and forge to the desired thickness, I achieve the pattern I want. After grinding, heat treating, grinding again, polishing, etching for 10-15 minutes in acid, cleaning in water, drying, and finally slightly polishing, we have the finished blade.
