Philips OneBlade Pro QP6510/20 is a representative of the popular OneBlade shaver product line. It is ideal for shaving, trimming beards and overall grooming. Use one blade to achieve a smooth shave and just add the adjustable trimming comb to trim stubble. With this hybrid product, you can set up to 12 trimming lengths, plus you'll appreciate its usability for both dry and wet shaving.

Package contents

In your Philips OneBlade Pro QP6510/20 shaver package you will find the following contents:

  • Philips One Blade Pro QP6510/20 shaver,
  • adjustable trimming comb with 12 lengths (0.5mm - 9mm),
  • charger.

Nothing is missing or missing. The packaging is handy so you can start shaving almost immediately.

Philips OneBlade Pro QP6510/20 shaver and its features 

This hybrid trimmer uses unique OneBlade technology, which combines a fast-moving blade (up to 200 times per second) with a dual protection system.

So you can shave and trim beards of any length, and thanks to the fact that it doesn't shave too short, you don't have to worry about injury or skin irritation.

And thanks to the aforementioned speed, you can shave in and against the direction of beard growth without worrying about painful snags.

The manufacturer has not prepared a product video for the QP6510/20. However, footage of the higher-end QP6520/20 is sufficient given the slight differences between the models.

Another advantage of OneBlade technology is that it provides exceptional accuracy even in hard-to-reach areas, and the positive news is that this device is completely waterproof. You can therefore use it for both dry and wet shaving and when cleaning it, just rinse it under running water. 

TheOneBlade Pro QP6510/20 is thus a safe bet, like all products from the Dutch manufacturer Philips. If you like to choose from more options, you might consider the equivalent of this model, which is the Philips OneBlade Pro QP6520/20. This offers a single comb attachment that is adjustable to 14 different lengths ranging from 0.4mm to 10mm

If you are interested in the features of the OneBlade product line, we recommend our summary article, in which we compared individual models in detail.

While the OneBlade technology is truly unique, it must be admitted that you won't get as close a shave with it as you can with top shaver models like the Braun Series 9 9290cc or Philips Series 9000 S9711/31. Still, it is rightly popular with many men who don't aim for a smooth shave.

Quality of workmanship and ergonomics

The Philips OneBlade Pro QP6510/20 shaver has an ergonomic handle that makes it very easy to handle. The black design with silver blade also makes this razor a very elegant affair.

Philips stuck to the idea that there is beauty in simplicity with this trimmer. On the front of the shaver, you'll only find a power button, a blade release button and a battery level indicator. The sleek black design won't let you down either.

Battery life and charging

The Philips OneBlade Pro QP6510/20 has a lithium-ion battery that lasts up to 60 minutes after an hour of charging. For safety reasons, this machine cannot be used with a power cord attached. Therefore, it should always be charged before use.

The advantage is the 3 LED lights directly on the handle, which will inform you of the battery charge status. This way you will always have an overview and will not be unpleasantly surprised, for example on the road.

In its category, when compared to other devices such as the OneBlade QP2520/30, both the battery life and the time required for charging deserve to be highlighted as strengths of this model.

Shaving

The advantage of this hybrid trimmer is the already mentioned OneBlade technology. If you use it without any attachment, you can easily shave by moving against the direction of beard growth. The shave is surprisingly smooth and, as long as you don't apply too much pressure, there is no risk of skin irritation.

For trimming, there is a special attachment for most common lengths in which beards can be grown. You can therefore choose beard lengths from 0.5 to 9 mm. The individual steps up to 5 mm have exactly 0.5 mm between them and this is then increased to 2 mm.

The design of the extender is solid, you don't have to worry about its durability.

If you want to use this product more for beard shaping, you will also be satisfied. This is because its body is tapered just before the blade. This gives you a good view of where you are with the edges of the blade and shapes your beard to your liking.

Like any other shaver, the OneBlade doesn't always capture 100% of the beard on the first stroke across your face. Sometimes you may even need to make multiple strokes, 3 back and 3 forth is common practice.

By combining a trimmer and a shaver, Philips offers the features of both devices.

Cleaning and Maintenance

The OneBlade blades are highly durable, guaranteeing you long-lasting, reliable results. The manufacturer recommends replacing them once every 4 months (if you shave completely twice a week). Of course, the blades can wear more depending on the type of beard. Their lifespan is thus rather short, which unfortunately increases the cost of running the shaver. On the plus side, changing the blades is quick and easy. 

When cleaning your shaver, you'll appreciate the aforementioned water resistance. Thanks to it, just rinse the Philips OneBlade Pro QP6510/20 under running water. 

The handle itself is of course covered by a 2-year warranty. You will have a hard time claiming used blades.

Spare parts

As mentioned, Philips recommends replacing the blades every 4 months, you can buy them either separately or in a pack of two. The blades are as follows:

  • QP220/55,
  • QP220/50
  • and QP210/50.

Also, you can get the Face and Body Kit, which includes:

  • 1 blade with body guard,
  • 1 face blade
  • and 1 body comb.

Use the body comb (3 mm) for easy trimming in all directions and avoid cuts in sensitive areas thanks to the protective blade attachment.

If you like to take your shaver on the go, you'll appreciate the option to buy a hard case. This will protect your shaver and all accessories from bumps, dents and scratches.

Who is the Philips OneBlade Pro QP6510/20 for

The Philips OneBlade Pro QP6510/20 Hybrid Trimmer can shave beards of any length and there is no need for additional trimming and grooming tools. This makes it ideal for discerning men who want a complete shave without the use of additional tools and accessories.

By the nature of the device, however, you can't expect it to shave completely smooth. So if you're more concerned about a perfectly smooth shave, you're better off looking for a conventional shaver. For a comparison of conventional shavers, see our blog.
