A wart itself protrudes above skin level and extends below normal skin level.

They have much more visualization than adjacent tissue, and you can see this in many medical diagrams.

When I cut, I do it horizontally in layers, until blood just starts to bead from cut vessels. In my experience, the wart will always start to bleed before the adjacent healthy tissue. The vessels naturally die back from the new surface, and the process can be repeated in a few days.

Interesting; are these (presumably clotted) blood vessels the threads that another comment mentioned? https://news.ycombinator.com/item?id=40417294

You can see a digram of the blood supply here [1]. If you look at this paper, you will find several warts with black dots. Those are blood vessels which have reached the surface.[2]
