Possible Title:
PfftGood Ones:Sailor’s port LEFT
One in an order NUN
Theme: double T’s replaced by double F’s in phrases
Cubicle reorganization? SPACESHUFFLE
Punching tool and {theme} FIST [F is T]
By the Way:Civil rights org. NAACP [I’d insert “One time”]
Some Nits to Pick:Armed to the max SAFEST [it’s not how many guns you have but where you are which determines one's safety]
Make the most of USE [the clue is too specific for the answer --- to use something does not suggest maximum efficiency, merely deployment. While it is possible to use something and by so doing use it maximally, the term needs a modifier to suggest that it was used so. For example, my merely using a saw does not in any way suggest that I made the most of the saw.
Sorry I left off the constructor's name. 5/13
