Ya ain't too fast for me and my machines now, are ya? Heh. Are ya?
The Engineer on faster construction

The Jag is a community-created melee weapon for the Engineer. It is a combination monkey and nut wrench, with a brown taped grip and a distinct curved upper jaw, similar to a Stillson wrench with a sharp point.

This weapon has 15% faster attack speed and upon being struck by the Engineer, speeds up the construction of any buildings by an additonal 30% over the stock Wrench, whether on initial setup or redeployment. As a downside, the weapon also has a 25% damage reduction, 33% damage reduction against buildings (making it remove Sappers in three hits instead of two), and 20% lower repair rate, making this wrench slightly less effective for maintaining a base or engaging in melee combat. Note that the 15% faster firing speed also means that you can repair buildings 15% faster, meaning that the 20% lower repair rate is much less impactful than it first appears. Switching from this weapon to the Gunslinger destroys the Sentry the player has built. Similarly, switching to this weapon from the Gunslinger also causes the Combat Mini-Sentry Gun to be destroyed.

The kill icon for the Jag was contributed by Psyke .

  • A jag, or "cleaning jag", is a tool used to clean firearms and thereby improve their efficiency.
  • The Jag was first found fully textured in the Team Fortress 2 game files after the Mann-Conomy Update, and was displayed in the Steam Update image for the Mann-Conomy Update. According to Robin Walker in an email to community author Jman, the Jag was originally intended to be a part of the Engineer Update, and was eventually cut when Valve could not figure out attributes for it. The Jag was later added to the game as part of the Australian Christmas update.
  • The Jag was submitted as part of Jman's submission into the Polycount Pack contest, the Jag Pack.
