What are the parts of a saw?

 There are many different types of saw, but most have the same basic parts.

Saw handle

The handle is the portion that's gripped by the user and is used to move the saw back and forth through material in order to cut it. 

Handles comes in several different shapes depending on the saw's application. 

Saw blade

The blade is typically made from steel and has a number of sharp teeth running along its bottom edge. 

The teeth are the part that penetrate the material first when cutting 

Front & back

When viewed from the side, the bottom edge of the blade where the saw’s teeth are, is called the front, and the opposite edge is called the back.

Heel & toe

The end of the blade closest to the handle is called the heel, and the opposite end is called the toe. 

Saw frame

Some types of saw, like this hacksaw, also have a frame which extends out of the handle and attaches to the other end of the blade.

All frame saws have removable blades.
