Experience the new standard with the Saber Cordless Professional Hair Trimmer. With a whisper-quiet digital motor and the perfect blade combination, the Saber crunches so loud you can hear the cutting echo. The combination of the high-torque brushless motor and the X-Pro blade with ""The One"" cutter can edge up with laser lines and also blast through bulk. For the Saber, this is just the beginning of the features and benefits. Touting a 4-hour cordless run-time and micro-usb port, it is a game changer in the shop, salon, at home and on the go. Unlike other hair trimmers, the Saber trimmer has a sleek and modern slim tapered design with a full-metal super-durable body. Incredibly, it only weighs in at 3.5 ounces, offering the ultimate in comfort and agility. The high-torque, low-vibration digital brushless motor runs at 7,500 RPMs, offering more power with efficient, quiet hair cutting. The digital brushless motor offers a power transfer that results in a smoother operation and reduction of heat.
