A writer for CNet got a hands on with the prototype: http://www.cnet.com/products/skarp-laser-razor/


Yes, I saw the videos... there were actually 2 CNET videos showing the Skarp, each slightly different. It is pretty horrible, honestly. The hair just bends, very few get cut. The glass fiber is so fragile it broke during testing. I know they say they are going to fix this all, but....    :popcorn:

But when I lifted the razor to my arm and placed the fiber against a hair, it cut right through. The laser actually worked. We tried it with light hairs and dark hairs, over and over again. Twice, we accidentally broke the fiber by getting the cheese-wire style blade caught on several hairs at a time, which definitely gave me pause

Skarp co-founder Binun says that with a mass-produced fiber and a AAA battery, the razor should have enough power to cut through five hairs at any given moment and keep cutting through more as soon as the previous ones fall away

Wow, so even the final design will only be able to cut through 5 hairs at a time!  :palm:
Newsflash - people are hairy, razors are required to cut through hundred of hairs at a time!
The average mans beard contains thousands to 10's of thousands of hairs.

Yet another stupid impractical product idea.

Now you are just making up straw man arguments. They say nothing about the time to cut 5 hairs. If they could cut those 5 hairs in a millisecond a whole face could be shaved very quickly. Try to attack ACTUAL problems with what is being said.

No, he's right. How would you get the blade to only touch maximum 5 hairs? If it touches only a few more, then there wouldn't be enough power for any hair to be cut.

Presumably the first hair gets almost all the power.

You must be living in another timezone - or actually another datezone.  It was suspended October 12, almost 8 weeks ago  :palm:

Yeah, they moved to Indiegogo because they didn't have a working prototype.

So as a summary... 

They got "kicked off" Kickstarter becaus they didn't have a prototype and what they showed to Kickstarter (when they sort of contested the "kick") was not prototyping looking enough.

Based on the cnet article (they tested the "prototype") : http://www.cnet.com/products/skarp-laser-razor/

They have a custom fiber "wire" and a laser which works at power low enough to make it possible to power the laser from batteries.
The current custom fiber wire must be stretched between the razor sides but it's also very fragile - it's so thin and fragile that if you press it on the skin it will break, in fact it's so fragile just pressing it against more than a few hair strands it will break 

They wanted the money so they could invest more than $100k into developing a less fragile fiber and they were hoping to glue somehow this fiber to the edge of the razor so that the instrument would take the burden, as in the hair strands would no longer put pressure on the fiber and it won't break so easily.

Even if much of the stress was relieved by the handle, fiber optics still don't like to be bent. Many shaving operations are not on a flat surface because the body's surface is not uniformly flat. It has positive (Riemannian) curvature on the chin, the jaw, the legs, and the mons; and negative (Lobachevskyan) curvature on the lip margins, the armpit, and the neck.

The kind of bends a razorblade can make are not really a problem for a fiber either AFAICS.

I don't see any problem there, normal razors are also rather inflexible, but body tissue is.
