Publication number: 20220072639Abstract: A reciprocating saw blade for a machine tool, in particular a jigsaw blade, includes a first row of saw teeth and a second row of saw teeth. The first and second rows of saw teeth are arranged at an angle to a longitudinal axis of the reciprocating saw blade. The angle of the first row of saw teeth opposes the angle of the second row of saw teeth. The reciprocating saw blade also includes a further row of saw teeth arranged between the first and second rows of saw teeth. The further row of saw teeth is set back, in particular suddenly set back, towards the longitudinal axis in relation to the first and second rows of saw teeth.Type: ApplicationFiled: November 17, 2021Publication date: March 10, 2022Inventors: Martin Kocher, Urs Karlen, Damian Brantschen, Daniel Grolimund
