Thanks to a clever design using a magnet and a cross-shaped groove, it is now possible, and easy, to hammer in a nail with only one hand.
A German hammer company named Picard designed the Latthammer with the intention of making it easier for roofers to hammer in nails overhead, according to Fast Company.
While being designed specifically for roofers, this hammer can help just about anyone looking to avoid a painful mistake while working.
