Comparison Panasonic ER-HGP84 vs Panasonic ER-GP80

Universal guide comb is an adjustable-height comb attachment that lets you make haircuts with smooth transitions without needing to swap attachments. You can change the comb height on the fly by simply releasing the latch and sliding the comb. Height-adjustable combs are great because you can cut with a single attachment, which also helps keep your workspace tidy. Naturally, this type of attachment has a complex design. The comb itself can be moved relative to the base that’s rigidly fixed to the blade, and to lock the comb in the desired position, you just press the latch. Due to the complex design, the attachment’s reliability is reduced, which is why manufacturers may include several universal guide combs in the set.

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.

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.

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.

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.

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.

— 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.

The clipper offers the capability to adjust its operating voltage, typically ranging between 110 and 230 V. Given the varying electrical network voltages across different regions (e.g., 230 V in Europe, 110 V in North America), this feature proves advantageous when using the clipper abroad. Some devices possess an automated voltage adjustment feature, requiring no user intervention, while others necessitate manual adjustment. It's important to emphasize this aspect before commencing clipper operation, and in cases of manual adjustment, it's crucial to verify the correct setting on the switch.

— 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.
