Effortlessly easy to use and ergonomically designed for comfort, the ES-RT37 has less cutting resistance with extra-sharp blades. Using three of the world’s sharpest inner blades, Nano particles are used to polish the blade edge to a fine tip of 0.3µm, 3 times sharper compared to conventional 1.0µm. This reduces the cutting resistance by approximately 1/2 for an effortless shave. In addition, the inner blades are arranged at a 30° angle to shave off hair horizontally for a more precise, close shave. Panasonic has created an electric shaver that delivers the closest shave possible through this technology which is normally reserved for the most expensive shavers. All Panasonic men’s shavers are 100% waterproof. Panasonic Wet and Dry technology has granted the flexibility of a wet or dry shave, and to give traditional wet razor users who enjoy the refreshing feeling of lather and water the same benefit from Panasonic's Wet and Dry shavers.
