    does an edge or a point ever end or does it cycle into another demention?theoreticly every bit at the end can be cut in half for ever but clearly the edge/point ends but where does it go?again the last bit we can imagine,can still but cut in half and that half in half lol so theres no end but there is,i say another demention whats your explination?

    As you either use the knife or sharpen it it is slowly falling apart. The little shavings that are seen when you sharpen the knife are what's coming off of the knife and will eventually be whittle down to nothing. Like everything it just gets worn out with time and the fillings go into your food. There's really anything to worry about for there aren't many everytime you cut up something. The metal won't hurt you, much.

    Your idea of a knife so sharp that its edge recedes infinitely into another dimension is mere dementia.

    If you see an electron microscopic view of a razor blade edge (sharper than most knives) you see that it's rather jagged and uneven. The idea of infinite sharpness is faulty.

    u missed my piont,literaly,lets make it the point of a needle,let say the last atom at the point of a needle=mathematecly you can cuz that atoms space in half and the half again for ever,omg you guys are not answering the question but like changing it and covering it,it cant mathematicly end and yall feed me something about a microscope,thats not going to cut it lol,look at the theory not what a microscope tells you,perhaps im not being comprehended,

    im looking for the mathematical answer for a point of a mathematical perfect needle,theoreticly speaking,=the last atom or partical can mathematecly be split in half forever,yet the needle ends in our demention clearly,shoosh lol

    The best you could hope for is a knife blade who's edge is one atom thick. Good luck keeping that together. Also the second anything so much as breathed on it your edge would fly apart to produce an edge many atoms thick. You can not make it smaller then one atom thick no matter how hard you try. In reality you would not even be able to get anywhere near this, I somehow doubt a million atoms thick would be realistic. I'm sure someone else can figure out just how thick that would be.
