Blade length adjustment
Adjusting the length of the blade allows you to change the cutting length of the cutting unit. Accordingly, this parameter affects both the trimming length and a more accurate haircut using attachments.
Blade width
The width of the operating tool (blade) of the clipper. A wide blade is important for head hair trimmers, as it allows you to capture more hair in one pass and cuts faster. In turn, beard and mustache clippers use narrower knives, which is useful for fine work to give facial hair the desired shape.
Width of the additional blade
By the width of the additional blade, you can determine its intended purpose. A 30-40 mm wide blade is usually used for cutting head hair, a 20-30 mm wide blade is most often used for beard and mustache trimming. Approximately the same width is needed for a blade for cutting body hair.
Power
The performance of the tool, the maximum rotation speed of the motor and how well the device handles with thick and coarse hair depends on the power of the electric motor. So, for cutting thick head hair, you need a clipper with a power of at least 15 W, the performance of such a device is usually enough to ensure a motor rotation speed of 10,000 rpm. But there are also more
powerful clippers(from 20 W). Trimmers for beards and mustaches usually need 5 W of power. Such models most often have a performance of 3,000 – 5,000 rpm.
Number of revolutions of the motor
The speed of rotation of the motor of the clipper. The speed of movement of the blades directly depends on this parameter, and the quality of the haircut, in turn, depends on it: the faster the blades move, the faster and more accurately the clipper cuts.
Weight
The weight of the clipper/trimmer is especially important when the device is planned to be used often and for a long time. The
less the clipper/trimmer weighs, the less the user's hand will get tired. Of course, there is a direct relationship between the mass of the device and its performance. Powerful clippers/trimmers use a larger and heavier motor. Additionally, the weight of the device increases due to the presence of a battery pack.
