  • $\begingroup$ If you mean the blade looking things that angle forward (top and bottom), they are wire cutters. The idea is that if a low flying heli encounters powerlines, those blades will cut the wires before they catch in the skids or rotor. $\endgroup$ – acpilot Nov 4 '16 at 19:47

    $\begingroup$ The entire "wire cutting" system is not just the knife, there is an abrasive strip running between the two windshield halves that scores the cable first, then the knife cuts it. $\endgroup$ – Ron Beyer Nov 4 '16 at 19:52

If you are referring to the angled pieces above the front window, and below the nose; they are referred to as the WSPS (wire strike protection system). Designed to shear a line before it wraps around the landing skids or rotor.
