Great Cleaver (3.5e Equipment)
From D&D Wiki
The great cleaver lives up to its name in that is it little more than an oversized meat cleaver when used. Build like a greatsword, the blade is thick, heavy, and broad. There is no stabbing tip, instead it is used more like an axe. Some Great Cleavers look like a cleaver, others have the handle inset into the blade itself. Regardless of how it looks, it is a powerful, but unwieldy, weapon.
The great cleaver is too large to wield in one hand without special training (the appropriate Exotic Weapon Proficiency feat). A character can use a great cleaver two-handed as a martial weapon.
