Upsetting steel is a process that shortens and thickens metal by compression. Essentially driving hot metal back into itself to create more mass in one area, the opposite of drawing it out. This technique uses focused heat and hammering to make parts of a bar larger for shaping purposes. This requires controlled heating and sometimes localized cooling to keep the swell in the right spot. #themoreyouknow @lipstick_blacksmith | JL Forge
