Yeah, I have had all of these concerns in the back of my mind, trying to reserve judgment until a prototype is up and running.

it just seems to me that one may be able to play with the edge geometry a little to make up for the brittleness of the ceramic; for example, make the cutting edge angle a little more obtuse than a standard razor, just enough to decrease the chance of flagrant chipping.

The appeal to me (and possibly many others) is that there would be minimal upkeep needed, no stropping, no rusting, and much longer between honings... if it can be made to work.

And it would seem to me that no stropping and less cleaning means less handling in general which means a decreased chance of dropping it.

though I may be wrong, I could see only needing a good flat piece of hardwood with diamond honing compound to keep it in shape, barring any large chips that would require regrinding

But I can see how this might all be a load of crap, but you never know till you try, right?
