You might not understand how truly useful and indispensable a Leatherman, or any multitool for that matter, is unless you've carried one for a while. Obviously, Leatherman President Ben Rivera is quite fond of his, but it caused a bit of a problem when he tried to pass through the gates at Disneyland while on vacation with his family. For perfectly obvious reasons, security there doesn't let people carry knives into the park. So after dropping his tool back at his hotel room, Rivera started thinking about how to carry the less offensive parts of his pocket toolkit in a more convenient way. Thus was born the Leatherman Tread bracelet.
