When the English and French general staffs were doing joint planning before WWI
(against the desires of their governments), Sir Henry Wilson (spit to get rid of
the taste) asked Foch "How many English soldiers would be of use to you in time
of war.?" To which Foche replied:, "One---and we will make sure that he gets
killed."
In something of the same spirit I would answer Mike's question "How many saws
constitutes a problem?" with "One---there will be more soon enough."
