Different sawing tools are applied for the different requirements in manual woodworking and are divided into the groups of frame saws and frameless saws.
Frame saws

The parts of a frame saw are called:
1. _________________________
2. _________________________
3. _________________________
4. _________________________
5. _________________________
- Frame saws are applicable for nearly all processes in manual woodworking.- The necessary tension of the saw blade in the frame is reached with the help of the saw arms, the saw knobs, the stretcher and the tensioning device.
- The saw blade can be fixed in any position to the arms.
Figure 9 Adjustable saw blade
- In frame saws there can be clamped saw blades with push-type or push-and-pull type cutting teeth.
List 1 shows frame saws with their features and application.

Frameless saws
Frameless saws consist of a saw blade and a handy grip. The saw blade has a sufficient stability or it is provided with a back support. Form and size of the saw blade as well as the tooth form are determined by its application. Table 2 shows frameless saws with their features and application.
