[meteorite-list] What makes a hammer a hammer?

[Michael Gilmer]

Hi Listees,

I have a quick question for the group - why are some falls not referred
to as "hammers" ?

For example, Allende and Holbrook are rarely referred to as hammers, 
but there are reports that both hit rooftops and other manmade 
structures.  Both falls are generally referred to as "historical" but
rarely as hammers.  Is there a reason?  Is it because the historical
element outweighs the hammer element in these cases?  Claxton is
well known as a hammer, but historically-speaking it's otherwise
unremarkable.  Is this simply semantics at play, or is there some
kind of formula at work?

Regards and clear skies,

MikeG
