    Well , there you go ... I always wanted to do a WIP , this has been by far my most ambitious project and I tried to capture the process as much as I can , I have to say ; with welding gloves about to catch fire it is not always to take them off and take pics but I have tried my best
    After loosing 8 blades due to strange cracks as if they were cooled way too rapidly ( not the case ) I had to stop what I am doing not to damage any customs In works due to rushing and wanted to tackle the task of making a knife out of tamahagane . This was acquired from a young japanese sword smith I met online
    I wasn't sure how much refined steel I would get out of the 800gr tamahagane so i kept my plans flexible .
    Fire in the hole
    It is covered in wet paper and clay to avoid de carburisation in first few heats . Initially steel feels more like a sponge , it is moving quite fast under gentle hammer taps

    Here after few heats and being squashed Into more manageable size

    Next fold
    It is at its 4th fold at this moment

    One more fold
    At this stage It is starting to behave like a simple carbon steel under the hammer , feels bit stiffer than what it was but no where near like chromium carbon steels like 52100 .
    I have lowered the temp on forge and started sunobe ( shaping into a blade )
    After 2 heats it is starting look like a knife

    After this pic I have forged the bevels more and it is at its final shape prior to heat treating , no pics of this stage

    Now cleaned up and covered in mud it is ready for thermal cycling

    Being normalised at this moment

    After 3 normalising cycles it is heating for heat treatment

    More to come

    It's about to being quenched in water , no stress , don't f this up [​IMG]

    After a heart stopping quench I haven't heard the ping and made few victory laps in shop [​IMG]
    Quick pass on grinder to check the hamon , so far so good
    After this I have polished with the sand paper I had in hand and continued with finger stones[​IMG]


    The other side , there is so much activity that I don't seem to be able Capture with my camera
    More to come soon

    Sometimes you just have to walk away from things and do something else. In your case the something else was really cool.
  4. Amazing looking stuff Mert can't wait to see more.
  5. Awesome project, looks like a lot of fun, and a great way to freshen your brain!
  6. This is like a really long ad break on your favourite TV program ....

    Can't wait for the next instalment.

    Thank you all , waiting to finish few customs and I will get this one finished as well . I have chosen mallee burl as handle material with copper , no frills no bling .[​IMG]
  10. Great stuff. A fan here of the less bling and frills;). Great 1st WIP. You need a buddy in there to take more action shots!
