I'm inclined to agree. If they're not working well and cutting air a few 
times makes no difference, then something needs to be done to adjust 
their attitude. To state the obvious, I would lubrificate them first. 
That's a word, isn't it? A nice light oil. And cut air some.

Then I would mark the mating surfaces with a Sharpie, cut air a couple 
of times, and examine to identify any problem areas that might benefit 
from the careful touch of a stone. Repeat process as necessary.

And if that fails... Check for curvature. Are one or both of the shears 
bent in a way they ought not to be? Consider straightening or adjusting 
by way of the application of brute force - ie in your vise. This is not 
quick and easy, and may not give perfect results, but you may possibly 
achieve some improvement if you go about it a bit at a time. OR you may 
break them...

FWIW
