OmniWrench Millennium 12
From Ratchet & Clank wiki
The OmniWrench Millennium 12 was a wrench made of Ultra-Light Teratannium and fitted with a hyper grip handle. It was built by Cronk and Zephyr[1]. Ratchet used the Millennium 12 in Ratchet & Clank Future: Quest for Booty. It functions the same as the other wrenches in the series only with some add-ons. The wrench will automatically home in on enemies when it's thrown. Cronk and Zephyr had also attached an illegal Kinetic Tether to the wrench, which allowed the head of the wrench to come off and attach to different objects, usually ones with a large flat bolt on them. This was the first wrench that features other uses than turning bolt cranks and swinging. Another feature was that Ratchet can pick up objects such as Helio-Grubs, Lava Rocks, or Undead Skulls and throw them.
