This noun literally means a cutting or incision, but Philippians 3:2 uses it as a derogatory wordplay for false circumcision. Paul warns 'beware of the mutilation'—using κατατομή (cutting up) as a contemptuous pun on περιτομή (circumcision). Classical usage shows notches, grooves, or incisions, and technically refers to mutilation as opposed to proper circumcision. The translation witnesses preserve the mutilation sense. By calling circumcision-advocates 'the mutilation,' Paul denies their practice has covenantal significance—it's mere fleshly cutting, not the true mark of God's people, which is now the Spirit's circumcision of the heart.
