Plunge-cut saw with scoring function

A plunge saw with a scoring blade ahead of the main one — the first handheld saw to carry the feature, and it solves the problem that laminate and melamine board chip on the underside as the blade exits. The scorer cuts a shallow groove along the line first, so the main blade breaks out into an already-severed surface. The result is a clean edge on both faces from the first cut, with no splinter strip to set up and no second pass. Track and depth adjust precisely, and the scorer switches off when the material doesn't need it.
