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.
Blades material/coating
—
Stainless steel. The standout feature of stainless steel is its exceptional resistance to rusting. When the clipper or trimmer boasts a sealed casing, the stainless steel cutting head can be conveniently cleaned using water pressure. While stainless steel is common in lower-tier devices and its blades can endure high temperatures, they tend to lose sharpness relatively swiftly.
—
Titanium. Titanium alloys showcase impressive durability against substantial mechanical strain. The titanium cutting edge adeptly manages hair of various thicknesses and densities, retaining its sharpness admirably. Tools equipped with a titanium blade are reliable for frequent usage, notably in beauty salons. However, the drawback lies in their notably steep expense.
—
Ceramic. Ceramic offers remarkable strength; its blades remain cool and sharp over time. Machines or trimmers featuring ceramic blades effortlessly handle even the thickest hair, allowing for frequent and prolonged use. Interestingly, models with ceramic blades often come at a more affordable price compared to those with titanium blades. Nonetheless, fragility is a significant drawback of ceramics; these blades are susceptible to damage from impacts and falls. Clippers and trimmers that are equipped with a ceramic cutting part must be handled with extreme delicacy.
—
Titanium ceramics.... Blades made of ceramic with a high titanium content. Ceramic in the context of the material used improves cutting performance, reduces friction and maintains a sharpness for a long time, and the titanium coating gives the blades strength, provides resistance to wear and corrosion. Titanium-ceramic blades are good for cutting coarse, thick hair, but they are quite expensive.
— Diamond. Diamond-coated blades have increased edge strength. Typically, these blades are based on steel, most often stainless, but thanks to diamond coating, the knife acquires higher reliability and durability. Of course, the presence of diamond coating on the blade significantly increases the cost of the device.
— Steel. Steel blades are the budget-friendly option. Steel performs effectively in devices used sporadically, mainly for home purposes. Although steel edges tend to lose sharpness relatively swiftly, their durability can be enhanced through the application of protective coatings like diamond, ceramic, or titanium. Clippers or trimmers with uncoated steel blades typically fall into the low-cost category.
— Graphite. Graphite coating is typical for stainless steel blades, it allows the blade to glide more easily through hair and skin and generally increases the efficiency and convenience of working with such a device. Most often, detachable trimmer blades are equipped with graphite coating.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.
Charging time
Time to fully (from 0 to 100%) charge the battery of the clipper. For rare cases of using the model, charging time is not so relevant, but for everyday use it is better to choose
fast charging clippers.
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.
