Advanced Performance Blade with Wide Tip

Perfectly honed to an optimal cutting edge, the durable, ultra-sharp men's hair trimmer blade is made from hypoallergenic stainless steel to ensure a comfortable trim with less irritation. This performance blade has an improved cutting edge: the blades are wide to enable the men's cordless beard trimmer blade to help lift and cut neatly through even the unruliest of hair, including whiskers that lay flat on the skin. With a rounded blade tip, you can create sharp beard lines when the trimmer is used vertically to the skin.

19 Length Settings with Trimmer Attachment

Create and maintain your style with the adjustable beard trimmer's quick-adjust dial. Positioned on the handle, the dial adjusts between 19 individual hair machine settings from 0.5mm to 10mm for exact hair length. The included men's grooming trimmer comb attachment snaps instantly over the blade to quickly and confidently trim, style and maintain beards and mustaches, as well as hair on the head and neck.

Ergonomic, Cordless Trimmer Design with Rubberized Grip

Sleek, lightweight and durable, the ERSB40K has a rubberized, ergnomic handle for optimum comfort, total control, and precise trimming results.

Corded/Cordless Convenience

Trim cordlessly at home or on the go. The ERSB40K can be operated as a cordless hair clipper or plugged into any AC outlet for longer corded use. The durable, rechargeable lithium-ion battery provides up to 60 minutes of power with each one-hour charge. A dual LED display indicates the 3-stage power and charge status.

Japanese Blade Technology

Every Panasonic blade is carefully crafted using a blend of ancient Japanese sword crafting techniques and modern technology. Each blade is constructed from traditional Yasuki Hagane steel, sharpened to a 30 degree angle, nano-polished and hand inspected to provide clean cutting strokes for an incredibly close shave that minimizes irritation.
