The Panasonic ES8101S511 men's shaver is a high performance, triple blade shaver that incorporates leading edge technologies to deliver superior results every time. Panasonic's Pro-Curve shaver has six unique features to give a gentle-on-the-skin, clean smooth shave. Revolutionary multi-arc foils fit uniformly against the skin, and the super flexible pivoting head rocks up and down to a maximum of 8 mm, and side to side up to 14 degrees, following the contours of your face for a smooth and comfortable shave. The inner blades have been sharpened using nano particle technology to achieve an extremely fine blade tip edge of 0.3 microns, reducing cutting resistance by half. Patented linear motor technology, featuring the world's fastest 13,000rpm, is designed to maintain full shaving power and performance when shaving tough whiskers, for a faster smoother shave until the very last seconds of charge.
