What are the uses of the following woodworking tools and how to distinguish them?

Chisels are used for planing, hollowing, planing and shoveling. One end of the chisel has a wooden handle and the other end has a tool steel bar with a blade.

Files are used to process places where planes cannot be processed, such as curved surfaces. There are many fine teeth on the wooden file, which is easy to distinguish.

Planer is used for rough planing, fine planing, material cleaning, light cleaning, starting, grooving, rounding, etc. The planer is to sharpen the embedded steel sheet with a width of 1~2 inches, and insert it obliquely into the shell of the wood planer, slightly exposing the cutting edge.
