The secret to splinter-free cuts is full material support at the cutting point. Trion jigsaw splinter guards are designed to be cut by the blade for perfect zero-clearance between the blade and the splinterguard. The resultant cut is clean through the entire piece with little or no finishing required. The D-handle PSB 300 features a finger tip trigger and smaller profile grip. The PSB 300 has all the qualities of the PS 300, with the addition of a comfortable D-handle for easy one-handed use.
