Strange Specialized Killstreak Australium Wrench

The Wrench, also known as the Uhlman Build-Matic Wrench, is the default melee weapon for the Engineer. It is a monkey wrench with an antique design.

The primary function of the Wrench is to upgrade and repair Dispensers, Teleporters, and Sentry Guns. In addition, while placed buildings construct themselves, striking them with the Wrench causes them to build 2.5 times faster. This effect is additive, with each consecutive swing increasing the build rate (up to almost double the default rate). Hitting buildings with the Wrench can also remove Sappers placed by enemy Spies.
