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.
There are many designs for anvils, which are often tailored for a specific purpose or to meet the needs of a particular smith. For example, there were anvils specifically made for farriers, general smiths, cutlers, chain makers, armorers, saw tuners, coach makers, coopers, and many other types of metal workers.
