Let me be the first to tell you that hammering hardened steel to flatten it is no easy task. It took several hours to achieve the thickness I wished for. By the time I was finished, I did not think I would be able to move my arm the next day.
Step 7: After you have hammered the metal down to the desired thickness, place the Railroad Spike into a bucket of water to finalize the thickness and shape of the blade.
Step 8: After you have achieved the desired thickness of your blade and cooled the metal then you are ready for the finishing touches. Use the File or Grinder to sharpen the blade and give it an edge.
