The leatherman squirt has a couple of variants, the ES4 is the first in this lineup with wirecutter’s and wire strippers in place of the pliers. I suppose one could, but—as with other tools on the Squirt—the tool's size will be its limiting factor. Eight bit options and a broadhead wrench and sharpener means you’ll have everything you need in one lightweight package. Premium blade material, stainless steel reinforced handle and fixed screwdriver mean you can clip it on and go.I have, however, used the Phillps screwdriver to tighten screws on knife sheaths and lamps and door locks, and used the regular screwdriver on a host of analogous tasks. Spring-action scissors and a variety of other features make the Squirt ES4 both versatile and functional. So go ahead, clip ‘em on and put ‘em to the test, these Portland, Oregon originals are built to last, complete with a 25-year warranty. A 154CM blade, locking carabiner-bottle opener and removable pocket clip complete this compact workhorse. There are other glass breakers and strap cutters on the market, but Z-Rex is the first one to pull together all the one-off features into one lightweight, intuitive and comfortable-to-use tool.
