    Old Discussion on W2 and Similar HT:
    http://www.bladeforums.com/forums/showthread.php/487641-W2-Heat-Treating-HELP

    Basic 1095 HT - Foolproof:
    Heat evenly to 1475F for 10 minutes then immediately quench in fast oil (fast enough to cool the steel through the 1200F-1000F in less than .5 seconds). For simplicity sake cool to at least 150F before tempering. This should get you a full 65HRC hardness with no problem, tempering should be done without delay. Tempering should be for 2 hours at the temperature to reach the desired final hardness. 400F to 450F is a good range for knife blades.

    Aldo's Steel HT and Spheroidized Steel threads ( New Jersey Steel baron)

    The steel from Aldo Bruno ( New Jersey Steel baron) and some other suppliers comes fully spheroidized. This means the carbon is balled up in balls and rods of carbides. This makes it easier to cut, drill, and file ... but has to be reversed in HT to get the steel fully hard. The below threads are on that topic.

    Hamon Threads and discussions

    刃文
    文 = blade 刃 = pattern


    Hamon - Ha - edge, mon - line/mark/wave
    ha-mon - the wavy line along the edge. In the old form, the word meant waves along the shore.

    Pronounced hah - moan


    Good discussion on making and polishing a hamon.
