B. F. Sword

The B. F. Sword is a basic item in League of Legends.

Description
The B. F. Sword radically increases the damage of anyone strong enough to brandish this colossal blade in battle.

Background
Forged in the fiery depths of Mount Gargantuan, its razor edge honed on the volcanic rock of Humongous Island, the B. F. Sword is the largest of its kind. Only those warriors with truly immense palms can wield such a blade in battle. In the right hands, this beast of a weapon can slice through multiple minions with just a single stroke.

Trivia

 * The name of this item is probably a reference to the B.F.G., a weapon from the Doom series of games which was often referred to as the Big F****** Gun. Sometimes players call it Big F****** Sword.
 * The B. F. Sword is the most expensive Basic Tier item.

Strategic use
If you are able to stay in lane long enough to afford a B.F. Sword early in the game you'll get a huge damage output advantage against your lane opponent.
