The Wave is Leatherman's most popular tool by far, and with good reason. The main blades, one straight, one serated are both accessible from the outside of the unit, so they can be quickly opened and using just one hand at that. These blades both lock in the open position for the safest operation. All the other tools have a locking mechanism too and the invaluable pliers are both needlenose and regular with hard wire cutters incorporated into them.
Leatherman are designed and manufactured by those who use what they make and care about the quality they put their name to.
