Hulk (Old Man Logan). 36,076 pages on this wiki. Between all of the above as well as not having occasional moments of heroism (like Ultimate Hulk and 616 Hulk) and not even having a sympathetic backstory (like Maestro) it could be said that this is the single most evil version of the Hulk in the Marvel Multiverse.
An anvil is a block with a hard surface on which another object is struck. The block is as massive as is practical, because the higher the inertia of the anvil, the more efficiently it causes the energy of the striking tool to be transferred to the work piece.
In most cases the anvil is used as a forging tool. Before the advent of modern welding technology, it was a primary tool of metal workers. The great majority of modern anvils are made of cast or forged steel (the latter is stronger) that has been heat treated. Inexpensive anvils have been made of cast iron and low quality steel, but are considered unsuitable for serious use as they deform and lack rebound when struck.
