Makita Jig Saw —
The blade holder on this Jig-Saw is held on by two Allen Head screws. The first time I used the saw the screws loosened and the blade began to wobble dangerously. Before I had time to react, the blade broke. Because of their location I don't see a way to tighten the screws without disassembling the saw. Not a good thing for a brand new saw.
