I am not an aerodynamicist, and would love a simple answer.
probably structural (easier to make strong) and also attached flow.
the leading edge of an airplane wing isn't a knife edge either.
from a glider builders forum.....
You dont want to have a sharp leading edge, because then the wing will want to chop through the air, and not fly smoothly. When the leading edge is pointed it has a greater tendency to want to hunt its way through the air. what i mean by this is that it will be flying one direction, and then a change in the air will cause it to move in a different direction very rapidly, and not smoothly like if it were round.
