    Trayton, I am fortunate by having this traveler`s forge..the charcoal really gets the steel up to forging temperature..this enables me to move thick steel faster..the hotter the steel, the faster you move steel with a heavy hammer...it will take me about two more days forging non stop to forge this chef knife to measurements..the next step will be to take it to the belt sander for final shaping and sanding..

    Niki, I am not confident in using forging thongs..it is difficult to keep the forged blade/steel secure when hitting it with a hammer, I previously burned myself when such a red hot piece of steel jumped out of the thong jaws and landed on my stomach...I really jumped around for quite a while, while conversing in French, Spanish and German,,at last I was able to say a few Afrikaans word as well when I looked at my shirt and see the enormous hole I burned into a nice , expensive shirt...I want to purchase large vice grips and weld elongated jaws onto it to secure the hot piece of metal ..to avoid such injuries in the future..

    I was nearly a hot mess...it is unbelievable how easy such a burning hot piece of steel burns trough skin and cloth..fast footwork ensured me avoiding a skin transplant for sure....

    Good, I am currently busy completing the large chef knife I forged from a thick piece of leaf spring steel.I do this in two stages..stage one being the forging of the chef blade from the leaf spring steel.

    Stage two:
    Doing straightening of the blade frame as well as forging the blade to taper from the spine to the bottom where the edge will be.

    Then forge a taper in from the back of the spine to the sharp point of the blade

    Stage three:
    Normalising the blade by bringing it up to forging temperatures three times and then let it cool in the fire until cool and the coals all burned out.

    Stage four :
    Grinding the shape finally and commence with a full face grind as all chef`s knife grinds are done.

    Stage five:
    Hardening /Tempering
