This is a anti-splinter guard for the BOSCH GST jigsaw.
It fits better then the original part.
I made some different widths of the slot because the saw blades differs a lot.
The original part does not fit so nice like mine and with some wider blades it will wear out and gonna be useless.
The first 3 times you need some force to insert an release the guard, so insert and release it first a few times.
I own the BOSCH Professional GST 18V-LI S (battery driven)
