The Leatherman Squirt PS4 tool is a compact, keychain-sized multitool with a handy set of pliers, and six other useful tools. The PS4 was introduced in 2010, and is still in production. The Squirt's knife blade, scissors and screwdrivers are accessible even when the tool is folded. That makes them much more convenient to use!
There are no similar tools from Victorinox or Wenger.
