Abstract: A deflecting and protective shield guard device, system and method of manufacturing and use is disclosed for utilization on or interaction with the lower or distal and proximately middle areas of a user's limb, when a user is exposed to a work environment where equipment is being used, or where ground or airborne particles, substances or debris are being emitted. The device has a shield body having connecting pairs of positionally opposing, end sections and lateral portions; and outboard and inboard surfaces. One end section is arced in shape, the other is sinusoidal, or in the nature of a periodic function curve having maximum peak and minimum sulcate portions; and each of the lateral portions is provided with configurations which exhibit wave-curve segment, arced, and linear, areas.
