Needle-nose pliers are the main component of the Free P2, and opening them is the best demonstration of how Leatherman has changed up the design from previous versions. When it’s closed, a set of magnets holds the handles together. One you push the handles apart beyond their magnetic field, the whole thing flips open freely—hence the name—like a butterfly knife. According to Adam Lazenby, the lead engineer on the product, the internal magnets are strong enough to keep the tool closed, but the magnetic field doesn’t extend much beyond the metal housing itself. As a result, it won’t attract other metal objects in your pocket or mess with your credit cards or electronic devices.
