Surfaced block

A surfaced block is a block of wood that has been made smooth and flat on the top and sides using a special tool called a plane. Think of it like smoothing out Play-Doh with a rolling pin so it's nice and even. Once a block of wood has been surfaced, it's easier to work with because it doesn't have any rough or jagged spots. It's like having a blank canvas to draw on, but instead of drawing, you can use it to make things like furniture or toys. So basically, a surfaced block is just a block of wood that's been made nice and smooth so people can use it to build things.
