Thread: Shaving with a ceramic knife

All that from a company who sold Contax/Yashica cameras at one time.

There's no doubt that that knife is definitely sharp. It whisked the hair off his head in a long smooth stroke without hesitation. My question would be how long could you expect the edge to hold up?

I also doubt his claim that it's the "world's first ceramic knife shave", but I digress....

I liked the video, personally. I just kept saying to the screen, "you missed a spot" until someone off camera pointed it out to him. lol

Unit: I wasn't aware people were getting ceramics that sharp. I stand corrected. I like a traditional straight too but I like to keep an eye on those trying new things and pushing things just for sake of it. Can't see me going ceramic, I like my carbon knives and razors but could see a place in the shaving world for a blade that doesn't need stropped. The only attempt I seen at a ceramic razor was pretty basic without lasers or batteries.

this sums up the video pretty well imho.


jaswarb : Metal is great at cutting things but we've been making metal blades for quite some time, maybe the ceramic industry just needs another few hundred years to mature. The test vid comparing it with a few other ceramic knives does show some flex in all, and a greater flex in the kyocera, video nicked from elsewhere, skip to about 4.20 for the comparison test:



It's certainly not the first attempt at a shave with a ceramic blade, but it's the first time I've seen someone being pretty happy with the result.

Well that is proof absolute(as though everyone needed proof) that I don't know everything.



My nephew will love seeing this in print.

I would never have thought that ceramic blades could be that flexible and not break. I might have to look into one.

I'd imagine eventually the cutlery companies'll beat the "shiny steel" guys with a ceramic core/edge with a steel outer layer bonded to it. The armor on the M-1 Abrams and current British main battle tank are layers of steel and ceramic sandwiched together, so it can probably be done.

Ceramic armour is not a new idea and has been around for a good long while. I don't see why a cutlery company would need to sandwich ceramic between metal. If ceramics can hold and maintain an edge why would the steel be necessary for? The blade in the two videos seems to be ready for regular use. I would like to see an all ceramic straight razor make an appearance.

I like it, it would be cool to have the blade look like a traditional blade though. Although that looked much easier to maneuver than a straight to me.

Ceramics are just too brittle. Maybe a new ceramic material? it seems to me a better effort in research would be with exotic metals to get a razor that is proper sharp and stays that way for a long, long time and yet can be honed by the average user.
