It's not okay to be dangerous with tools.
Dad brings his young son into the garage where he has set up a work space for them with wood and power tools, so they can build a bird house.
Dad wants to introduce his son to woodworking and carpentry.
Dad shows his son how to properly and safely use a jigsaw and watches him make practice cuts on scrap wood before cutting the pieces for the bird house.
Dad hands him a jigsaw with the safety disabled and tells him to cut along the line.
His son learns to be confident with power tools and learns to use them safely and properly, and they complete the bird house.
The son pulls the trigger while holding it near his face and the noise scares him, and he cuts his fingers as he drops the saw.
