Big Idea Design With a lineup of titanium pocket tools and pens, Tennessee's Big Idea Design has established a name for itself in small, lightweight everyday carry (EDC). Its new Bit Bar Inline shrinks and lightens that EDC even more, giving carriers Phillips, Torx and slotted bits inside a sturdy all-metal driver that should easily fit in the small fifth pocket of a pair of Levi's jeans. With the Bit Bar Inline, Big Idea brings together its tool and pen lineups. The new compact driver has a titanium square-tube outer chassis sized like a pen, complete with pocket clip. The three bits are stored on the removable inner bar and a spring-action ball bearing and rare-earth magnets help keep things secure.
