Roughly the size of a cigarette pack, the TiNexus packs a working 72-tooth ratchet that engages with just 5 degrees of wrist swing — enough to drive a screw in tight spaces without repositioning your hand. Two foldable plates hold 20 quarter-inch bits in place magnetically, and an integrated extender locks into an L-mode for torque or an I-mode for reach. It weighs 1.13 ounces on its own, about half a full-size ratchet head.
