How can I use a tool to create rounded edges on wood?

To create rounded edges on wood, you can use a tool called a router. A router is a power tool that can be equipped with a roundover bit, which is designed to shape the edges of wood into a smooth, rounded profile. Simply adjust the depth of the bit and run the router along the edges of the wood to achieve the desired rounded shape. Be sure to wear appropriate safety gear and practice proper technique when using a router.
