{Referring to Mach}
We are in agreement that the square rectangle stain marks the hilt (handle) of the knife. Only Mach is misstating the evidence by his BS mock-up, ignoring empirical knowledge (how images are made by, for example, letter-press or block print).
I went so far as to do some experiments on a kitchen knife coated with watered-down spaghetti sauce (a blood substitute in this experiment). Here's a photo from the experiment; the handle is on the left, the cutting edge of the blade to the top. The handle (part toward blade) is more in contact with the paper towel under the knife, and creates a rectangular stain. There's a gap in the stain between the handle and the blade, because the contact points are, in the ideal limits, the tip of the blade and the handle section nearest the blade. The stain is larger because of the low viscosity of the watered spaghetti; it flows. And the blade may bend to a degree.
