Impact driver

An impact driver is a tool that dad uses to put screws and nuts into things like wood or metal. It has a special mechanism inside that helps daddy to screw them in tight without hurting his arm or wrist like he would if he used a regular screwdriver. It's like having a helper who can make the screw go extra tight and fast without daddy having to put in a lot of effort. It's a really useful tool for making things strong and secure, like when building a treehouse or fixing the fence.
