To saw a straight line, tilt the saw forward slightly. Then the cut
already made will help guide the blade, and it is easier to sight the
straight line along the blade. To saw curves, keep the blade
perpendicular to the metal. Tilting the saw forward while rounding a
curve will pinch the blade causing it to break prematurely.
To make a sharp turn, continue the same up and down rhythm without
any forward pressure. Then slowly rotate the metal around the moving
blade. On each downward stroke, make a slight sideways cut until you
reach the new direction.
