<VV> 1 inch nut tool.

[N2VZD at aol.com]

KD tools made one like the one pictured. Mine had cut outs for measuring  
line sizes on it. It has its uses , but  I have much better ones made by  
Matco. Number is SPW143. I think Snap On made one like it also.
They do not jump or slip , and work perfect on modulators also. They are a  
Strong , thin ,smooth , open end configuration. Pictures available if 
needed.  The MATCO site is a pain to navigate.
