Most BIG commercial towers are the kind that come to point at the bottom.
This design helps to reduce torque stress on a tower (I think). Most ham
towers are "flat" on the bottom.
The pointed ones use a "pin" of some sort and require guying of some sort
from the first section. The flat ones eventually require guying at some
point.
I prefer the flat type since it is easy to temporarily remove a set of guy
wires to slide an antenna up the side of a tower. One can not do that with
the pointed type since it must be continuously guyed.
W2GD was recently injured by riding down 30 feet of tower that was "secured"
by a pin. Accidents can and do happen on both types of tower.
