With woefully inept sharpening skills, I find myself in need of 
sharpening an old pair that belonged to my mother.  If she were still 
with us, she'd be 116; so these are, indeed, old ones - at least 75 
years old by my own observation.

Can anyone point me to a good wiki or online article that describes the 
appropriate process?  There is a screw holding the 2 arms together.  Can 
this be removed?  Is the thread right or left handed?

Thanks for any help.  I want to get this pair sharp and give it to my 
daughter as a gift from the grandmother she never knew.
