    You have to bevel a blade leaving a thickness at around 1,5 mm . the blade was finshed now with 120 coarse paper .
    Now you have to draw the shape of the blade on a see-through sheet .
    [​IMG]
    on which you have to mark the hamon line
    [​IMG]
    Cut from the sheet the line of the hamon and use it for making both the side of the blade .
    The mentioned step is quite important in order to have symmetrical hamon line

    No we start :

    Let it dry for at least 24 hours
    Now it's time to temper the blade ( I am using a gas forge ) .
    Heat the blade to the right temperature , then quench it in water for about 3-4 seconds , then immediately finish to quench it in oil

    Let the blade getting cold and then start removing the oxide layer with 60 grit belt and then continue polishing
    grit 60
    [​IMG]
    120, then 240
    [​IMG]
    up to 600
    [​IMG]
    800 ,1000
    [​IMG]
    soldering the guard
    [​IMG]
    [​IMG]
    After perfectly degreasing the blade , sink it for 4-5 mins in a moisture made up of 1 part of ferric chloride and 5 part of water
    [​IMG]
    Remove the oxyde left by the chloride washing the blade with soap and water
    [​IMG]
    Repeat this step three times ( chloride-washing) in order to let the chloride going deeper in the steel
    [​IMG]
    Now sink the blade in water mixed with baking soda to quit the effects of the chloride
    [​IMG]
    cover the blade with a lot of oil , pack it in paper and let it rest night time
    [​IMG]
    [​IMG]
    then I start to roughly polishing the blade with a cotton wheel and some green polishing paste .
    The blade before the bodyshop polishing paste
    [​IMG]
    After the polishing paste
    [​IMG]
    Blade is now finished
