The Forever Sharp range by Rowenta includes innovative hybrid trimmer-electric shavers with durable self-sharpening blades. Hence the name Forever Sharp. The double-sided blade is made of high-quality stainless steel and features self-sharpening technology designed to last for the entire service life of the appliance. The double-sided blade profile provides excellent visibility and maneuverability, making it easy to create perfectly even lines and shave hair with both upward and downward strokes. For length control, the devices come with a set of removable combs (standard 1, 3, and 5 mm, with more in extended versions), turning the shaver into a full-fledged styler.

The appliances are designed so that the blade does not sit as close to the epidermis as in classic rotary or multi-foil shavers. This guarantees complete protection against cuts and mechanical irritation, making the device absolutely safe even for use on sensitive areas of the neck. A powerful motor with a maximum speed of up to 8,000 rpm also plays an important role in reducing irritation, allowing the blade to quickly and effectively handle hair of any thickness in a single pass, preventing snagging or pulling of hairs.

In addition, Forever Sharp electric shavers stand out for their phenomenal battery life, surpassing many classic shavers. In most cases, the built-in lithium-ion battery provides up to 120 minutes of continuous operation on a single charge, more than enough for one and a half to two months of regular grooming. The long battery life is complemented by support for fast 4-minute charging, enough for one complete shaving session. A proprietary connector is used for charging. In addition, many models feature a small built-in display showing battery charge level information.
