摘要

The sawblade (1) and its production method involve a blade with irregular contour edge lines and with saw teeth along the whole or parts of its irregular line. It is produced out of a plate body, especially from a carbon steel-quick steel or bi-metal plate body in different stages. Out of the plate body are stamped a number of holes by a stamp tool which has hole stamps in a pattern corresponding to the contours around the sawblade and its teeth. Out of the plate body, a number of holes are stamped as in the previous stage. The holes from both stages produce a toothed sawblade, the teeth of which have inclinations from two opposite directions.
