ABSTRACT OF THE DISCLOSURE A hand portable chain saw with a movable safety bar for actuating a chain brake has a bracket and a lineally-acting spring which together provide a detent for holding the safety bar in the nonbraking operating position, but yet accelerate the braking movement of the safety bar upon disengagement from the detent. The carrying handle for a portable chain saw encircles the top and both sides of the saw housing to enhance both oper- ator safety and convenience. The brake-actuating safety bar on the saw has a similar wrap-around contour to ensure engagement by the operator in the event of untoward movement of the saw for essentially any sawing position.
