The Leatherman Squirt ES4 tool is a compact, keychain-sized multitool with wire strippers, and six other useful tools. The ES4 replaced the Squirt E4 in 2010, then was retired circa 2019. No current Leatherman tool includes the calibrated wire stripper. Too bad, because it was the perfect small pocket tool for anyone who works with electronics, robotics, or other small-sized wiring!
There are no similar tools from Victorinox or Wenger.
