When do you call something a Hitch or Half Hitch?
i see the terms sometimes used interchangeably; or what is a Hitch on a post becomes a Half Hitch if on a rope?
What are the visual and mechanical differences is something that has kept me awake a few nights. i think it goes by pattern, flow of force and reversibility of this flow (and still have same form of mechanics for that module). i think there is 1 unreversible form of Hitch(if reversed forms a different mechanic), but several forms of Half Hitches (preceding another knot/anchor, an indirectly trapping Hitch around self after a Turn around mount and a Half with better nip) that are all reversable(opposite end can be pulled to invert to same mechanics). i'm not to sure we should define something as a Hitch on a firm/hard mount (wood); but as a Half on a 'soft' mount (rope).
i think defining these most basic pieces of the puzzle will help form the whole picture more accurately. i think many lessons in these basics can be L-earned from the most basic knots of the Square/ Reef to SheetBend family/ class. Also that rigging is like enlarged knots/ knots under a microscope; so that they can reveal more of their secrets.
