Hand tools for turning nuts and extracting nails can be a man’s best friend—or foe. These innovative new grippers are designed to deliver unparalleled leverage and versatility, making it easier than ever to squeeze into tight spots to dislodge a rusted nut or extract a headless nail. Now there’s no excuse not to DIY.

Your jalopy requires a different repair at every stoplight

Solution
The Bionic Wrench

The eight-inch-long Bionic Wrench adjusts easily to fit any bolt or nut from 7/16 to of an inch (or 11 to 20 millimeters). Squeeze the handle, and six piston-like steel levers close in to grab the nut, equally distributing force across the flats so that you don’t strip it. $29
