This screwdriver might be named “PLUS” but it’s actually what’s been subtracted that makes it more useful! The basic shape of a screwdriver isn’t all that conducive to maximizing manual power. Add in a simple space through the handle, however, and you can maximize pressure to turn while easing your grip and using another to twist. A set of two is all you need to tackle odd-jobs and household tasks or even serious mechanic work! Designer: Wang Tong
