Abstract: A top-handle portable working machine includes a grip configuration that makes it easy for a worker to manipulate the implement as intended in order to adapt to tasks in which accuracy, fineness, or an attractive finish is needed. The direction of an axis in which the top grip extends and the direction of a working axis of the implement are inclined relative to each other in a vertical direction so as to intersect at a point to the rear of the housing at angle between 15 and 25°. A detachable grip-position restricting member is attachable to a concave part of the top grip.

Abstract: The invention provides a chain saw attachment for unobstructed cutting of smaller objects with diameters less than three inches and larger objects with diameters greater than three inches. The attachment includes a set of prongs that vertically extend at an acute angle from a cover above the cutting teeth of the chain saw blade to a specified distance below the blade. The prongs stabilize small objects from whipping and dragging when engaged by the cutting teeth and facilitate the cutting of brush with diameter equal to height of the blade. Moreover, the cover does not extend the full length of the blade to allow for fully unobstructed cuts using the uncovered section of the blade. The cover increase safe operation of the chain saw and distributes stress from a particular prong over the entire attachment.

Abstract: Embodiments include a sharpening fixture adapted to mount to the nose of a chainsaw guide bar. When mounted, the operator may direct a force towards the guide bar thereby causing a linear directed actuator to move a sharpening element into engagement with cutters of a saw chain to sharpen a cutting edge of the cutters. In various embodiments, the actuator is biased such that when the force is no longer applied, the actuator pulls the sharpening element out of engagement with the cutters.
