The knife you take to a whole, pretending the pieces were always separate.

means A distinct part cut or divided off from a larger whole.

from From Latin sectio, 'a cutting,' built on the verb secare, 'to cut' — the same root that gives you saw, scythe, and segment. Romans used it for the literal act of slicing something apart before English borrowed it for the tidier, paperwork version: a piece defined by where the cut was made, not by any seam nature put there first.
