If ever there was a multi-tool designed for backpacking light, this is it. The PS4 is the newest of the smallest and lightest Leatherman line. The previous models gave one a choice of either pliers or scissors, but not both. This new model has both. The weight is less than two ounces.
The Leatherman PS4 has a small but strong pair of pliers with both round and flat surfaces, perfect for gripping bolts, wire, etc. At the base of the pliers is a wire cutter. The pliers have a spring system to open them.
The knife blade is 1 1/2 inches long, made of high quality steel, and very sharp. Though not designed for heavy cutting or whittling, it seems adequate to every task one is likely to encounter short of a bear attack.
A double sided file has a rough side that works well on wood and a fine side that works equally well on fingernails and most metals.
The scissors are tiny but being very sharp, they work surprisingly well. They cut paper, cardboard and any cloth up to and including heavy-weight codura. They make cutting moleskin or duct tape to an exact size very easy.
The tool has two screwdrivers, a small and a large. The large includes a canopener.
This last weekend as a buddy and I were coming off the mountain, a clip holding a pin on his backpack got pulled out as he slid down a trail with rocks and branches on the sides. Both the clip and the pin disappeared in the snow and he was suddenly without an attachment for one shoulder strap. Using this tool, we were able to pull a clip off of his snowshoes but the pin was too short. We were able to use the wirecutter to cut a new temporary pin out of a piece of heavy wire from elsewhere on his frame and the pliers to make a stop at one end and a loop at the other to put the clip into.
Great light tool. The best currently available.
