Hi guys, my first post on instrucables. I've made a bushcraft knife out of RWL34 stainless steel. This so that it can be used for canoeing on salt water. RWL34 is a high carbon(so good edge retention) powder steel from Sweden. I heat treat this by heating it up to 1050 degrees Celsius in a stainless steel envelope. Once the kiln is back on temperature I leave it there for 12 minutes. When I take the knife out of the oven I clamp it between two steel plates for cooling. Tempering is 2X 2 hours at 200 degrees c.
Please ask if you have anymore questions. I'l try to answer them!
