How I make a knife
I look for old used metal files. The old ones are usually 1095 high carbon. I look for the Nicholson, Arcade or Heller brand. New files made in China are low carbon and case hardened this makes them unsuitable for knife making. Old sawblades and car leaf springs are really good too.
I then take the file and put it in the forge where it is heated to approximately
1550 degrees. I might hammer it out on a anvil to the rough shape or just turn off the forge and let the steel cool slowly inside. I usually won't mess with it for at least 6 hours while it cools.
Once cooled hard but brittle file is now soft and ready to shape. It can be filed with another file or metal can be removed with a belt grinder. I have a few basic paterns that I use for the rough layout but I just grind away until i like the feel and look of the blade.
I like to color outside the lines so no CNC, Plasma or waterjet cutters here. every knife is different. You won't find 50 of the same thing for sale. If you're looking for the flawless, perfectly machine cut knife, skip to the end.....
