Drawing Styles and Modelling
A saw used to make straight cuts in metal. The blade is held in tension in the frame with the teeth pointing forwards. The blade can be turned at a right angle to the frame for long cuts by rotating the bolts in their square holes.
The junior hacksaw is used for straight cuts on small, light work. The blade is held in tension in a sprung steel frame.
A Coping Saw
A saw used to cut curves in thin wood and plastic.
It may also be used to remove waste from joints. The teeth point towards the handle to cut as saw is pulled. The lever pins turn to change the position of the blade. The handle is normally made of beech wood and when turned creates more tension on the blade. The frame of the coping saw is made from sprung steel.
