JHM is one of our exclusive, in house, anvils available at Anvil Brand. JHM Anvils are forged in a Texas Foundry, where they are poured with the state-of-the-art forging technique. Each anvil is tested for integrity and inconsistencies, then shipped to our facility in Illinois. Here, the final touches, including painting, machining and finishing before the anvil is shipped to you, the customer. They are cast from ductile iron and have a rockwell hardness between 48 and 52. We pride ourselves with 100% satisfaction, and have rarely had a return for a JHM Anvil. JHM Anvils are also available to our international customers in Europe and the UK, exclusively at Hand Made Shoes Ltd.
