Glossary

Fixed combs (straight)

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.

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.

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.

Features

Self- sharpening blades. Blades made using a special technology, thanks to which they sharpen themselves, due to friction against each other in the process. Thus, the blades remain sharp at all times, and their maintenance is limited to the replacement of worn blades.

Function of thinning. Thinning in hairdressing is called cutting the ends of the hair at different levels — as a result, after the haircut, the hairstyle looks more natural and magnificent. In machines, special thinning nozzles are usually used for this.

Wet cleaning. The clipper's capacity for wet cleaning of its attachments, allowing them to be rinsed under flowing water, is a notable feature. It's important to clarify that this pertains exclusively to the attachments – not all models with wet cleaning have waterproof casings (see below). Nevertheless, even without a waterproof casing, it might still be feasible to clean the attachments without detaching them from the device. In general, wet cleaning is frequently more efficient, quicker, and precise compared to dry cleaning.

— Waterproof body.In this context, a sealed enclosure is indicated, enabling the machine to withstand water exposure without adverse effects. The extent of protection can vary; certain models tolerate brief water immersion, while others can operate even when submerged. These specifics should be detai...led in the accompanying instructions. Nevertheless, for clippers used in environments with elevated humidity (like bathrooms or wet areas), having such a water-resistant enclosure is greatly preferred, and sometimes obligatory.

— Built-in vacuum cleaner. The clipper is equipped with a vacuum cleaner, which greatly facilitates cleaning after cutting. The suction hole located under the blades sucks most of the cut hair into a separate reservoir. Of course, there will not be a 100% return, but there will be much less hair scattered on the floor. However, when cutting a beard, a vacuum cleaner will do just fine.

— Laser pointer. The presence in the electric razor of a laser in the form of a straight line. With its help, you can easily, and most importantly, evenly and symmetrically trim the desired areas.

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.

Material

— Metal. High-end clippers/trimmers use a metal body. Typically found in professional models, and occasionally in semi-professional ones, a metal casing ensures remarkable durability and resistance to heavy use. However, this design substantially elevates the device's weight and cost.

— Plastic. Mostly low-cost clippers/trimmers are equipped with a plastic case. The plastic case is lightweight and easy to care for. Among the shortcomings of plastic, only low strength can be noted. If you intensively use a trimmer/clipper with a plastic case, then the working surface of the device will quickly become covered with scratches and scuffs.

— Metal/plastic. Semi-professional clippers/trimmers commonly feature a combination of metal and plastic casing. These models incorporate metal with plastic inserts. This approach maintains a high level of reliability while using plastic inserts to lower device costs and enhance user-friendliness. Clippers with combined casings are versatile for both home and salon use.
