7 is reasonable, particularly  as Mike has suggested with multiple styles, such
as a "gent's saw", etc.  Now if one of the seven is one that you have made, your
number automatically doubles to 14, as it does if you have sharpened at least
half of the saws in your possession.  If it can be proved that you have actually
used at least one of the saws and have cut at least one drawer's worth of
dovetails in the past year, the number of saws you can own is now unlimited.

I think I have maybe a dozen or two DT saws, but they're not my problem!
