Upgrades, repairs, and speeds up construction of friendly buildings on hit

"I do a little bit of everything."

The Wrench is the default melee weapon of the Engineer. It is a monkey wrench of standard design, with wooden grips riveted on. While the Wrench is equipped and is not being swung, the Engineer will constantly smack it against his palm, creating a soft plapping sound effect.

Unique among melee weapons, it is used to speed up the construction of the Engineer's buildings, as well as heal and upgrade them - including those of allied Engineers. Enemy buildings are instead damaged as usual, including that of the Spy's Sapper, which takes two hits to destroy. It can also defuse the Demoman's Dynamite Pack by whacking it - but not the secondary dynamite sticks. When striking a building-in-progress with the Wrench, it speeds up the rate of construction by almost double, which is additive for multiple Wrenches. If the building is constructed, and the user has sufficient metal, the Wrench will allow upgrading that building by up to 25 metal per swing. If a building is instead damaged, the Wrench will use that metal to repair it, up to 102 damage per hit. The Wrench itself does not facilitate building, as that is the job of the Construction PDA.

As an actual weapon, the Wrench does not see nearly as much use. While it's useful for killing cloaked and disguised Spies, the Engineer's low health and average speed means that rushing at enemies with the Wrench will not end well. His Sentry Gun is likely to kill anything within its proximity anyway, and if the user is setting up a base, then the Shotgun will see much more use. As damage from the Sentry Gun counts towards the Wrench's random crit chance, it has a much higher than expected rate of random crits, and so might be worth using against overhealed enemies who are too focused on killing a Sentry Gun to notice its owner swinging right at them.
