Chipmunk....Yo! Thats great! I carry 2 of those in my pocket. So simple yet so effective. Where I work lots of grindng goes on (The Angle Grinder Type...so don't get excited!!)I've had Grinders, Drills & Welding plants full of Carborundum, tracking power to metal parts, even on Class 2 gear.
Cheers. J2R
