Ooooh! [UB], a cutting remark. |
|
|
Now there exists technology to deposit a thin film of diamond on various substrates. Too expensive so far for consumer products, but why stop at ceramics? Deposit a diamond film on, say, titanium nitride coated steel, etch away the steel and you might get a blade thin enough to be slightly flexible despite the extreme hardness. |
|
|
Some microtomes already use diamond knives. Microtome knives of any kind, including steel, are the scariest sharp things I've ever worked with. They are basically super-razors. |
|
|
Actually, [TD3], Gillette coats the Mach3
with diamond-like carbon (DLC), and
now Schick has a product with it as well.
(See link).
The New Yorker had a surprisingly
interesting article about the
development and launch of the Mach3. I
never could understand why Gillette
didn't promote the diamond coating
more. |

Cryogenically freeze the razor and DLC coat it. The carbides rise to the surface during freezing and create a great rough carbon surface for the amorphous diamond molecules to adhere to. |

I always chuck my multi-bladed disposable heads long before the sharpness wears off. it's impossible to clean out the crap in between the blades. It's $6 a blade in new zealand for the schick version. This means it's basically $6 a shave unless I want to spend 20 minutes trying to wash the goddam head. |

I think a better idea is to revert to the old-style double-headed disposable razors (the kind vampires cut their tongues with), but create a razor head that can hold multiple double-headed razors. Maybe three. A switch on the side will rotate them so that either one side or the other is angled properly for shaving. And when it is full oc rap, pop the top off, wash each blade individually, and put them back in. Those double-headed razors are cheap anyhow. if they were made out of ceramic all the better, though i like somewhat bendy razors when i'm using razors for non-shaving tasks. |

[edit] Additionally you could create a small 'razor clean-n-sharp' gizmo that sucks in dull grimy double-headed razors, and polishes and steel-sharpens the edges before spitting them out the other side. |

Thus your razors can last you for a long, long time. |
