2 forms of Half Hitches can be used to nip the Bitter End, such as seen in Bowline and Sheet Bend.  If the loop can actually pinch/nip INTO a contained rope depends on the tensioned rigidity of the Half Hitch as vice of the jaws driven by arc tension vs. the encompassed rigidity.  Or if not rigid enough to bite into the encompassed to nip
