Micro-Caliper

A Micro-caliper

A micro-caliper is a small tool.

While attempting to diffuse the Romulan mine that had attached to the hull in 2152, Captain Jonathan Archer used a micro-caliper to work on the mine. (ENT: "Minefield")

Also in 2152, Commander Charles Tucker used a micro-caliper to adjust a component on a 31st century communications beacon. (ENT: "Future Tense")

The Starfleet micro-caliper doesn't seem to be anything other than simple pincer-pliers.

In 2374, Entharan arms dealer Kovin used a micro-caliper to remove the guidance system casing of his particle beam rifle while showing it to Seven of Nine. In Seven's false memory where he assaulted her, Kovin used the micro-caliper to remove her ocular implant. (VOY: "Retrospect")
