Reviews: Norelco Beard Trimmer

You have finally achieved a milestone of manliness; you can grow a full beard. Your grandfather and father showed you how they shaved with a razor, but their lumberjack/hippie days were long gone by the time your first two facial hairs appeared. So how does one get from a full bush to a well-groomed, trimmed beard? Good thing it is your birthday today because your girlfriend just handed you a box labeled Norelco Beard Trimmer: the best beard trimmers in the USA.

What Is a Norelco Beard Trimmer?

 A Norelco beard trimmer is a handheld device that replaces the scissors and razors that are time-consuming and not designed for close up, small-space, precise trimming cleanups. Beard trimmers cut, but don’t draw the blood. Beard trimmers trim but don’t require the time and patience needed to use scissors. Requiring far less cleanup than the shaving foam and razor duet, beard trimmers are also self sharpening.

How Do Beard Trimmers Work?

Norelco beard trimmers— like all beard trimmers— work their magic through six basic components that can be modified according to design and function.

  • Body
  • Shave head
  • Cutter
  • DC motor
  • Trimming adjustment
  • Internal circuitry


The magic of a Norelco beard trimmer is encased in a durable plastic casing that conforms to the hand and is easily gripped. Beard trimmer bodies can have a banana shaped feel with a Star Trek appearance. They can also come encased in sleek and sexy stainless steel. They usually come with a thumb slideON and OFF switch.

Shave Head

The shave head is a removable component that glides through the beard during the process of trimming. The shave head comprises two parts; the plastic comb and the base. The comb feature is the part that that deftly slides through facial hair as the Norelco beard trimmer is gently stroked along the cheek. The comb ensures that the underlying blade cuts, but does not pull the facial hair.

The plastic combs come in different sizes and are easily swapped out, depending on the length of facial hair desired. Removing the plastic comb reveals the shave head beneath. The shave head also has a base and a movable comb. The comb is affixed to pivots on either side of the base and helps to straighten facial hair so that there is no hair pulling as the beard trimmer glides along the cheeks.

The base has a comb-like aspect on the upper side to accommodate the blades of the cutter. The shaving action relies on steel rods maintaining the flexible movement of the shave head and is dependent on the comb being pressed down to align all the parts in such a way as to achieve the trimming outcome. The shave head is a mechanical spring action structure that resembles the chewing motion in humans.


The cutter is that part of the Norelco beard trimmer that actually trims facial hair. There are two stainless steel blades in the cutter component; one is stationary, and the other oscillates back and forth and in an elliptical motion.

DC Motor

The motor drives the cutter assembly by making the movable blade oscillate rapidly.

Trimming Adjustment

The depth or length of hair to be trimmedis modified by varying the distance between the shave head and the cutter. Trimming depth adjustment can be achieved by a simple slider to position the shave head, a rotary mechanism or by changing out the size of the plastic combs.

Internal Circuitry

The innards of a Norelco beard trimmer include a charging port and a power supply. The power supply happens to be the only electrical part of the trimmer, and it provides energy to the motor. It also manages the battery during cordless operation.


Norelco beard trimmers can be purchased from Best Buy, Kohl’s and Dillards, but we like the selection, ease of shopping and rapid delivery of Amazon. If Amazon doesn’t have it, then we shop at Dillards. Norelco beard trimmers can also be purchased at Walgreens, but the lack of selection makes it wiser to buy elsewhere.

In a perfect world, there would be the perfect Norelco beard trimmer that was precise, quick, maintenance free and never pulled hair or irritated skin. Since this is not a perfect world, Norelco beard trimmer’s need to be taken for what they are; a way to groom and trim body hair so that the user feels good about himself. All trimmers are ergonomically designed so that they fit well and feel good in the hand. Some trimmers have a thumb operated rotating wheel to adjust the settings; others do not.

There are titanium blades and stainless steel blades; both blades get the job done. Some beard trimmers clean up quickly with water; others need water plus a brush. All Norelco beard trimmer blades are oil free and need not be replaced except for the OneBlade Pro, which requires a swap out every four months. Having to swap out blades every four months is a deal killer.

The Philips Norelco beard and head trimmer series 5100 is a letdown. It’s relatively cheap but obviously for a reason; if it doesn’t work well with all beard lengths then it doesn’t work. Rather than designing for 0.2 mm increments, it should have been designed with durable plastic and the ability to prevent pulling hair.

The Philips Norelco OneBlade Pro is a NO because if we wanted to continue replacing blades every four months we would continue to use a standard razor. The last straw is its tendency to lose its gentleness when the device glides across the jawbone.

We like the Norelco beard trimmer 3500. 20 length settings with a single comb and 0.5 mm precision settings delivers a lot in a sleek and sexy easy-to-grip handle with the thumb operated zoom wheel. Given its size and cost, we’re not surprised about the vibration, nor the lack of contour conformity.

Of all the Norelco beard trimmers reviewed, we liked the 7300 the best, but it is now a discontinued item. While discontinuation does not deter most people from purchasing such a shaver, if we are going to spend the money, we would like the availability of replacement parts.
