Prolonging the life of Gillette Fusion razor blades


First, a short warning - razor blades are sharp - they have to be - and I´m not responsible in any way if you cut yourself by following the instructions provided here !-)

Also, if you have a very (very) sensible skin, this article is probably not for you...

Still reading? Gillette Fusion razors are a great tool to get a clean shave but - at least in my opinion - there is some planned functional obsolescence in their blades.

Wearing off...

On the left you can see a new blade and on the right another one which has been used three times a week for around three months (already longer as suggested by the producer btw). The green strip situated over the three cutting blades - called Lubrastrip by Gillette - does a lot of the "(pro)glide" action thing (lubrication...yeah) and also serves as an indicator to actually show the overall wear of a blade.

However, it also provides some planned obsolescence as it wears down very fast by losing some of its height with every shave (easily explained with some lubrication material being taken away during each single swipe).

(The angle measurement above is solely based on the photographs and doesn´t represent the angles as they are in reality - in addition there is at least some inaccuracy caused by perspective distortion)

With the Lubrastrip wearing off, the cutting angle of the blades changes gradually over time making the shaves less effective and more...itchy and scratchy?! You don´t want this, do you? Consequently you get the blade replaced by buying a new (plastic-blister-packaged) one and you trash the old one (just as the plastic-blister-packaging...).

A simple solution

So, what can be done to at least prolong the life of a Lubrastrip razor blade - yes - replace the worn Lubrastrip.

The requirements of a replacement will be the following:

  • Fast and easy to acquire / produce

  • Comparable height as original Lubrastrip

  • Soft (not too soft), smooth, water- and stubble-resistant surface (we don´t want material degradation)

  • Easy to attach to mounting of original Lubrastrip

  • Not skin-irritating / toxic (minor problem regarding the small amount of material used in this case)

So what´s the solution?

I used a 1.3 mm copper wire isolation.

With the wire torn out (of course)...

...and cut to the right length (approx. 32 mm) it fits the Lubrastrip mounting quite well.

To fix it, I glued it in with a thin line of cyanoacrylate glue (aka super glue - no it´s not toxic but actually even recommended for treating minor lacerations).

Here a comparison between a new and a repaired replacement blade:

The angle is as good as new:

I have been using this method for some time now and it helped me reduce the number of used blades per year significantly. Thus it´s a good example of "Reduce/Reuse/Recycle" in my opinion...
