The ROCKET contains a strong magnet located under the cap within the tool body. It's used to hold the tool to the cap, which is affixed to your lanyard, and to hold in the scissors & hemostats. Because the magnet's field extends beyond the body of the tool, please be aware that it could interfere with pacemakers and other sensitive electronic equipment within the magnetic field.
Keep the tool at least 4 inches away from any sensitive electronic equipment. If you have a pacemaker, we recommend using the pocket clip to keep the tool away from your pacemaker. More about magnetic field safety here.
