Tweezers

The Tweezers (ピンセット) or Pincet Glove (ピンセットグローブ) is an attachment-type manipulator for microscopic object interference. Used in the Elementary Particle Engineering Laboratory to allow the researchers to grab particles, it is a plot device that led to GROUP's discover of DRAGON in their attempts to escape the grasp of the Dark Side of Academy City.

Etymology
The word "Pinsetto" is a loanword of the Dutch word "Pincet", meaning "Tweezers" in English, the Baka-Tsuki translations uses the English as equivalent instead of a direct transliteration.

Principles
It is essentially some mechanical fingers that let you grab particles that are even smaller than atoms. It was created to use things like magnetism, light waves, and electricity to “absorb” these particles. It is normally kept in a larger form to help keep it from being stolen. When in it's optimized form it looks like a metal glove. The index finger and the middle finger each have a long glass claws coming from them and the glass claws had what looked like even thinner metal stakes in them. On the back of the hand was a small monitor that looked like a cell phone. The glass claws extract the particles and the metal stakes inside carry out various measurements.

Battle Royale Arc
Kakine Teitoku stole the Tweezers from a Elementary Particle Engineering Laboratory in District 18 near Kirigaoka Girls' Academy after much effort against ITEM, in an attempt to get a hold of one of the UNDER_LINE. He used it during his battle with the Professor of to discover him using Mimosa. Kakine later made use of it to find UNDER_LINE, though was apparently unsatisfied with what he saw, deciding to kill Accelerator instead in order to force Aleister Crowley to negotiate with him.

After defeating SCHOOL, Tsuchimikado Motoharu of GROUP recovered the glove from the remains of Kakine Teitoku in the aftermath of his fight with Accelerator and used it to decode data from a UNDER_LINE. Doing this they discovered the name DRAGON alongside those of GROUP, ITEM, SCHOOL,, and.

Dream Ranker Arc
During the growing fad of Indian Poker, scientists began using the cards to store information as insurance. Suspecting that information related to the Tweezers might have been stored in this way, Gokusai Kaibi requested that Yobou Banka investigate the possibility. With his abilities, Yobou began by identifying online discussions about the cards with any indications, however unlikely, of the Tweezers. This led to SCHOOL sending thugs, and later, Yumiya Rakko, after Saten Ruiko, on discovering that she had purchased a card produced by someone who could pick up the smallest things with "chopsticks". Yobou personally investigated another lead at a research facility, where he used his ability to copy the contents of the Indian Poker card stored in the vault onto a blank one.

Some time after Rakko's defeat at the hands of ITEM's Frenda Seivelun, SCHOOL had acquired the Indian Poker cards with useful information on the Tweezers, namely that it would be used within the next few days for an experiment at a facility near Kirigaoka Girls' Academy.
