OK, so square (four sides) is better than slot (two sides), and
octagonal (eight sides) is even better than four sides, the logical
conclusion would seem to be than the more sides the better.

Take that to the limit as sides - infinity, and you get what must
be the best of all: round drive (or as it is usually known: cheap
philips head screws after use with the wrong sized driver).


There's probably some truth in that... But remember the bit you used to
make the round isn't making a good quality round. It's kinda like those
Combo drive screws or the square drives that are almost, but not quite,
compatible.

Make a good quality round, use a good quality round bit, and pull rather
than push and the screw will come out easily.

(Do be careful not to make the round too round. You might wind up cold
welding the bit to the screw. :-))
