If you think about it, a crowbar already comes vaguely sword-shaped (or as sword-shaped as any long metal tool can be). You just need to hammer down the curved end of the crowbar to create a hilt and then sharpen the straight edge to create the blade. To add flair to the super simple concept, Miller Knives gave the sword a stylish curve. You can’t even tell the beautiful weapon actually started out as a lowly crowbar.
