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.
Number of length settings
The number of haircut length options provided in the design of the clipper or the design of the nozzle. The more such options, the more versatile the clipper and the more cutting options it provides.
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.
Power supply
—
Mains. The clipper is powered by a 230 V electrical network. The benefit of this power source is the unrestricted operational duration (no need for periodic battery recharging). However, drawbacks include the necessity of an available electrical outlet and the limitation imposed by a power cord, which can impede movement and cause operational inconvenience.
—
Battery. The clipper is powered by its own built-in battery. On the one hand, this gives maximum freedom of movement (since there is no power cord) and battery life — such devices can be used even where there is no electrical network. On the other hand, the battery life is limited, it must be constantly recharged — otherwise there is a risk that the charge is exhausted at the most inopportune moment (for example, during the haircut).
—
Batteries. The clipper is powered by interchangeable batteries. In terms of its primary pros and cons, this power source resembles battery power (as mentioned earlier). However, in contrast to built-in batteries, replaceable batteries offer less capacity, making them suitable for low-power devices like nose trimmers (see Type) that don't demand prolonged usage. On the positive side, replaceable batteries allow for swift replacement when depleted, whereas a built-in battery would necessitate a lengthier recharging process in such instances.
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.
Additionally included
—
Scissors. The inclusion of a set of scissors with the hair clipper enhances its value, catering to both experienced enthusiasts and professional hairdressers. This bundled option provides a comprehensive haircutting package, and the scissors serve as a valuable tool for addressing finer details that the clipper may not handle alone.
—
Comb. Availability in a set of delivery of the clipper of a comb. A comb is one of the most necessary tools for a hairdresser, so when purchasing it together with a typewriter, the user gets rid of the need for a separate purchase.
—
Charging stand. The stand serves a dual purpose as a charger and storage unit for the machine. It facilitates convenient recharging during quick intervals between cutting sessions, making it ideal for hairdressers to keep the machine on the stand while using scissors or other tools. Additionally, it can double as an accessory stand (see Stand for accessories).
—
Stand for accessories.The stand is designed to store clipper accessories such as detachable nozzles, cleaning brushes, and oilers. Using this dedicated stand reduces the chances of losing any of these accessories. In cordless clippers, this role is frequently fulfilled by the charging stand, which also serves as a storage solution (refer to Charging Stand).
—
Case. Cases include all kinds of rigid structures for storing the clipper. Cases in the form of handbags made of thick fabric also fall into this category. In addition to reliable storage of the device, they also elevate the model to the highest class. In low-cost clippers, a much more primitive fabric cover is included in the package.
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.
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.
