Fixed combs
Clippers and trimmers are often equipped with fixed-height removable combs. The more combs in the kit, the smoother transitions the device can make. The standard set usually includes 3-5 combs, more advanced models may have 7-10 combs of a fixed height in a set.
Haircut length
The cutting height is influenced by the type of cutting element and the inclusion of detachable combs. Toothed blades can trim hair as short as 1 mm. By coupling a toothed blade with a detachable comb, the cutting height can range from 2-3 to 20, and even 30 mm – the precise height hinges on the provided comb attachments. There are defined minimum and maximum cutting heights. The minimum pertains to the blade's inherent capabilities, devoid of attachments. The maximum cutting height is determined by the detachable comb type.
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.
Operating time
The typical duration of uninterrupted operation for a clipper powered by a self-contained source (battery or rechargeable batteries, refer to Power Source) without requiring a recharge or battery replacement. Extended continuous operation time becomes particularly crucial when intending to use the clipper in locations where recharging or battery changes are unavailable, such as during long trips.
Charge level indicator
The charge level indicator allows you to know the status of the battery, its degree of charge. Achieved using the built-in display or LEDs.
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.
