Constantly hammering your fingers instead of your target nail? ThumbSaver spares your thumbs by using a powerful magnet to keep your hands far away from nails, screws, staples, and anything else you’re about to pound (or screw) into a slab of wood, while its bright red rubber grip keeps it easily visible inside that mess of a tool box.

Cover your bases with a two-pack (both the regular and mini versions) at Amazon – 10$.
