May I divert the thread a smidge and ask what, if anything, can be done 
for scissors that are too tight?  I have a vintage pair that cuts fine, 
but is just tiring to use, since it takes greater than normal effort to 
open and close them.  Unfortunately, the screw is peened over, so it 
won't loosen.
