Individual Razors

Next step for a close and sensitive shave

Let's face it, hewing down stubble with deft strokes of a sharp bit of metal is very crude. And for many, myself included, it easily leads to rashes due to the freshly hewn ends being sharply pointed and pointing at skin.

This idea, without having to use RFID or custard, changes all that.

The individual razor is a simple concept: a razor blade cuts one hair at a time. The unit has multiple such blades. As many as possible.

The front tip of the unit resembles a single-line scanner in both form and function - it digitises the stubble. Behind that are the array of razor blades; controlled by a biaxial piezoelectric mechanism to position themselves in line with a single hair.

These razors, having aligned themselves to a hair, rotate themselves rapidly such that the end of the hair is cut in a nicely rounded way.

Needless to say, no soap is required; and special firmware will allow specific styles to be produced; or even beards maintained precisely.

       I kind of like the idea - and imagine a big glinting mask that can be donned by the (fearless) bestubbled.   

       One really good way to cut down on unpleasant razor-rash is to use a brush properly, and most importantly, to shave *lightly*. We're led to believe that we should be dragging these things into our skin in order to get a proper shave - not so! Shaving is like mowing a lawn, setting the mower too low does nothing but dig into the turf. Razors should be effortlessly glid (glid is to gliding as flown is to flying) over the face in a series of smooth motions.   

       The proper way to do it is to use a brush, and to spend some time working up a lather on the face. It's the lathering process itself, using a brush, that lifts the hairs and suspends them in the foam, ready to be cleanly snicked off with your chosen blade. Of the total shave-time, at least 70% should be spent properly lathering up.   

       Then, preferably using a straight-edge razor, the lather can be removed, along with any bristles using as light a touch as possible.   

       Post shave, a quick rinse in hot, then cold water - followed by a slapping on of a chosen aftershave to tighten the pores. It should sting ever-so slightly.

       //glid// glad? glade?

       Yes, I'm not sure what the right thing might be.
Glewn? Engloden?

       glode? glidden? Actually, the past participle of "glide" is just disappointingly regular - glided. (Like "elide", "side", and "tide"; but not like "hide" or "ride", in spite of sharing their Middle English ancestry).

       In this idea, are you pressing your face into a bowl, the interior of which is lined with umpteen whirring razors?

       [caninemorningsnack], not quite. Think more of the 'electric razor' but with many cutting blades, individually controlled to target individual hairs and cut them with nice soft round ends.
vincevincevince, Oct 28 2007

       So, how long is shaving time expected to be? And how many blades do you think would be on it?
rascalraidex, Oct 28 2007

       The shaved area generally consists of fewer than 15k hairs. With a microarray strip of one hundred individual razors, each able to cut ten hairs a second, that gives a theoretical shaving time of 15 seconds. Practical shaving times are more likely to be in the region of 60 to 90 seconds to account for the fact that it will be difficult to stop wasting the razor array by overlapping previously shaved areas; and that in sparse areas the array will be at suboptimum efficiency.

       Does anyone else remember the Mad Magazine spread from the late '70s which prebaked most of the ideas in this category?

       I think it may be nice to have nano laser razors that can sing hair off. I have more hair than both my parents and not they are not apes or monkeys as some of you would think. I am just so hairy that it keeps me up at night. I wonder if there was a painless hair removal system that was idiot proof that stopped burns, cuts and scrapes.
