Lately I've seen commercial ads for "Self Sharpening" kitchen knives by "Calyphon" very clever short few seconds ads showing kitchen knives being inserted into storage wooden blocks where they are being automatically sharpened by tiny little robots after each use!

Anyone seen them and bought them?
Do they self sharpen as advertised or are we being lied to by marketing BS?
Sounds to good to be true doesn't it?
Do you remember good old "Ginzu" knife infomercials, where they would spend 30 minutes cutting all kinds of materials to proof that their knives never get dull?
Now, I never owned them so I can't say if it was indeed type of knife steel that never gets dull or not, BUT I always thought they were made from some kind of hard tool steel that retained its edge for long time. So at least it was believable.
Now, these new self sharpening knifes with zero proof defies all belief!:grumpy:
PS would it not be cool if it was true and knifes could self sharpen themselves, especially kitchen knives????
