Every man needs to know how to use tools. Hammers, table saws, you name it. But they can also use some help every now and then, which is where the Wise Hammer comes in. It automatically detects studs in the wall, which makes hanging up that family photo just that much easier. Not only that, but the hammer also has a built-in marker, so you can go pick up a nail without forgetting where the spot was. Despite it being Wise the hammer sadly won’t prevent you from hitting your hand instead of the wall. It’s available now for $29.99.
