It seems that each year, that would be an electric shaver that guarantees "a closer shave". But what does it mean? How close can your shaver get that it doesn't involve the removal of the skin from your face? It feels like we've reached the end of the line, folks. This is as far as the technology train can bring us when it comes to "a closer shave".
Then, Philips asked us to hold its beer and released the Shaver S9000 Prestige.
The latest advancement for the Shaver S9000 Prestige is the NanoTech precision blades. These blades are imbued with nano particles, which makes them stronger and with longer-lasting edges.
The science of blades
Colour us sceptical. So we did a little light reading into this. Before NanoTech, there were diamond blades—where the blade is applied with a nanocrystalline synthetic diamond coat. Then, it is polished until its cutting edge is a few nanometres thick. And if you are curious as to how small is a nano; a nano is one-billionth of a metre: the width of a paper sheet is about 100,000 nanometres thick.
Then there are silicon blades, which are repurposed from silicon wafers (thin slices of a semiconductor). With a cutting edge of a few atoms thick, its sharpness is almost akin to a diamond.
Again, these coatings are meant to prolong the blades' sharpness but when it comes to rotating blades, it's a challenge to retain its keenness. Not only are the blades moving at an incredible speed; they are also are exposed to wear from hair cutting hair and the elements like moisture from the user's skin and environment. And let's not forget technology scaling, where components in gadgets reduce in size.
With these in mind, Philips created the PressPerfect Project to create better blades. The project was completed in 2016 but that gave the group a better understanding of the treatment of stainless steel, which brings us to now.
So, the Shaver S9000 Prestige uses NanoTech blades, which cuts extremely close to the skin and lasts longer. Other than its multi-direction ContourDetect heads and waterproofing feature, the shaver's head has SkinComfort rings that have anti-friction coating that allows the shaver to glide over the skin and now you can charge the device wirelessly with the Qi charging pad.
The Philips Shaver S9000 Prestige retails for SGD599 and is available at leading electronics stores, major department stores and selected authorised dealers.
