Every you need to know about handsaws
THE BASIC'S
- The best handsaws are mad of fine-tempered steel and have shaped plastic or wooden handles.
- The main difference between handsaws is the shape, number and pitch of the teeth. These variations make them suited to either cutting timber across the grain or with it, along curved lines, or through metal, plastic or plasterboard.
- To prevent binding, saw teeth are usually set, or angled, away from the blade so that the kerf it cuts is wider than the blade's thickness.
- Generally, the more points or teeth per 25mm a saw has, the smoother and slower it cuts.
- Most saws sold in Australia are imported from America and Europe, and usually cut on the push stroke.

Crosscut saw
This has knife-like teeth that slice through wood fibres. Use for cutting timber across the grain. Standard blade length approximately 500mm Teeth per 25mm 7-12
HINT For a really smooth cut use a saw with 10-12 teeth per 25mm. |

Coping saw
This steel-framed saw has a long, narrow,
flexible blade that can be rotated to any angle. The blade is pulled taut by turning the handle of the frame. Use for cutting small curves in timber. Standard blade length 150mmTeeth per 25mm 12-18HINT To make an inside cut, drill a starting hole then slip the blade through it before attaching to the saw frame. |
