Today’s invention was going to be a new way to ensure that the crud which clogs every multiblade razor was no longer a problem. I’ve had to accept that the build-up of this debris is currently a too-hard problem and also that it’s actually a big part of the razor business model: people won’t throw their blades away so quickly if they can clean them out (despite ‘developments’ like the flexible cleaning bar and the scraper).
Instead therefore, today’s invention is a much less ambitious tool, which enhances the established business model of disposable, expensive aftermarket refills.
Each razor unit would now be sold with a void in the handle into which a small vial of shaving gel could be inserted (this might then be diluted by adding eg hot water). This works in the same way that a toothpaste pump does. Activated by pressing the blade unit to the face, gel is gently squirted onto the face in front of the blade.
The gel might also contain some bicarbonate to give a refreshing “phizz-shave experience” (TM) -or not. Perhaps this fizziness could also help reduce the concretion of debris and allow running water to actually wash away some of the muck. A weakly endothermic fizzing reaction would not only cool the skin, reducing any tendency to razor rash, but also cause the facial hair to stand on end and make for an even closer shave (or at least a more colourful marketing message).
It may be possible to arrange that only a very thin film of soap is applied to the skin, via this controlled delivery method, thus creating less debris and prolonging the life of the shaver itself -so that customer dissatisfaction is reduced to a manageable level.
This also means you never have to carry a giant aerosol with you when travelling and allows the manufacturers to charge even more for their shaving accessories.
