I respectfully disagree, Dick - the sharp point helps dissipate and lower
the risk of a strike. Blunt points grounded with VERY heavy conductors
like seen on power comany switch/breaker stations are designed to handle
strikes - just like the top of the Empire State Building.
The open mesh stranded conductors on the old(and most new) lightning rod
installations are of pretty large OD, but small ampacity, and were mostly
copper clad steel. They wouldn't even handle an average strike(18,000
amps), but they sure handle a lot of charge dissipation.
