Hammer Tail Cove

[Richard Brekne]

Hi Jon..

Aerodynamics !...  The cove provides a kind of spoiler affect that helps 
keep the hammer on track at high speeds. 

And if you believe that, I have some property just outside of Basra you 
might be interested in :)

Seriously tho.. I never really thought about this.  I would like to 
think the must be some kind of a reason for this beyond visual 
esthetics... but who knows ?  I will be interested in hearing what the 
others have to say.

Cheers
RicB
