Rusted Railway Track Forged into a Beautiful KATANA

It took me almost a week to hand forge an Iron railway track piece into a long Metal Strip and this was one of my hardest forging ever. I don't have a power hammer so i did all the forging with hands and turned a railway track piece into an almost 35 - 40 inches long steel strip.
Grinding:
I started all the grindings of long strip on my SURFACE GRINDER and turned the forged strip into a Katana shaped long steel piece. I also hand sanded the edges with the help of file to remove almost all the roughness of the sword.
o. I made the Blood Groove with the help of dewalt roater.
o. The blade bevel was made by my professional angle grinder and 2x82'' Belt grinder.
o. Hand Sanded the blade to remove roughness.
Hardness:
There is a professional way to harden a Katana and that is
Covering the whole sword in a Fire Clay (Insulation) Except the blade bevel.After that we put the sword into the fire and heat it to critical temperature. We use oil to Quench the heated sword in it. Now the Bevel is hard and the remaining sword is annealed. Tempering the blade is the best way to increase the Strength, Hardness and Toughness of the sword.
Hibaki:
This piece is traditionally made by forging some copper or brass but we can also make it by casting these metals. And the purpose of hibaki is to hold the Sheath with the handle.
Handle:
The Handle contains three parts.
o. TSUBA: I made the guard by Wax casting technique and also used some black epoxy resin to make it more beautiful. Tsuba shows a partition between the handle and the remaining sword.
o. Spacer: This is the little metal piece which fits on tang and controls the fittings of the whole handle so nothing should vibrate in handle.
o. TSUKA: A nice piece of wood uses as a handle/ tsuka of the sword and that could be Wrapped by some soft Silk or leather strips.
