By "tip" i meant to say "edge." The thickness at the very edge is never going to be 0, but at the very least probably around 0.1mm
I think if your knife is .1mm at the actual edge, it will be really dull. Idk if the following is a razor or a knife, but 1 micrometer is a thousandth of a millimeter. The image is from Definitions of Sharp and Keen Anyway, I think @noj responded accurately.
