Amazing tool, would highly recommend to anyone!
The Leatherman squirt PS4 is a simply amazing multi-tool. It packs the punch of a full size multi-tool in a small package. It is the light-duty reincarnation of Leatherman's Wave. It features a fantastic tool set made from high quality materials in a very small and lightweight package.
Despite the size and weight of the squirt, it does not at all feel cheap or flimsy, all the tools and strong and as thick as you'd expect and hope to see from Leatherman. The pliers are light duty as you'd expect, but for their size they are extremely functional., they are also spring loaded, which I have found very useful, particularly on a tool this small. The wire-cutters work well, although I have only tested them on cable no hard wires as of yet, although given the light weight nature of the tool, I don't anticipate every testing it on anything hard.
The blade is 420HC steel as standard on all basic Leatherman multi-tools, it is chisel ground, but ground well and therefore is very sharp and holds a good edge. The file, I cannot praise enough, unlike the nail-files that are standard on most multi-tools of this size, the PS4 features a proper three-sided metal file, it works very effectively in any task from fixing your nails to de-burring a piece of copper pipe.
The screwdrivers are also excellent on the PS4, it features a flat head driver and cap lifter/bottle opener, the flat head is strong and very functional, the tool has no noticeably twist when driving screws, the flat head can also be used as a try tool to great effect. The cap lifter works as expected, a little on the small size, but it works none the less, and to be honest, the cap lifter is somewhat less than high priority. The 2D philips driver also works excellently, it's functionality doesn't seem to suffer from the lack of a full 3D driver, and turns screws without issue, I have noticed some marking on the edges of the Philips driver, but really nothing worth mentioning, as this is a light duty multi-tool.
The scissors are good, very strong and sharp, I have even managed to glide them when cutting wrapping paper. Using the spring alone they do not open very far, but really how far do they need to open. The spring is very strong and I cannot imagine it ever breaking under stress.
Overall there is little to nothing that I can really criticize about this multi-tool, it's well made, constructed from good materials, it feels solid, and despite its size I still feel better prepared from having it with me on a daily basis. It's strong enough to perform useful jobs, yet small and light enough to never need to leave it at home. I see people complaining about all Leatherman tools, mainly how they managed to break them, but if you use this light-duty multi-tool for light-duty tasks then I cannot anticipate you ever having issues with it. Some may also find the price a bit steep, but for the quality and innovation you receive, I personally believe that its a good investment and worth every cent.
