Leatherman Squirt PS4
I’ve been carrying around the Squirt PS4 all summer. The knife, pliers and wire cutters have all been getting a work out and have held up fine. The screwdrivers and scissors are also very well built for their size. I’ve had larger Leatherman tools and smaller multitools, but this is the sweet spot for me in size and functionality. Red, Blue and Black colors are available. Amazon sells them for $25.
The PS4 fits in my watch pocket with plenty of room to spare. It measures 2.25 inches long (closed) and is about half an inch thick.
If you prefer needle nose pliers with a great range of wire strippers, but the same form factor as the PS4, consider the ES4.
