A forge is a hearth used to heat materials like Damascus billets so its shape is malleable when forging. Forges can also be used for other effects such as tempering, hardening, or annealing. Our selection of forges feature insulated doors on either side for a smooth process when entering and removing materials. They operate on propane or can also be configured with natural gas.
