If you have no P.H.D., you are a not a fence man. Get an extra for the beginner who thinks it is a spud bar and beats the blade flat and breaks the handle. "I don't know why it broke. All I did was spread the handles 6' wide." Don't tell them not to grip both handles separately. I like to watch them bang their knuckles together. The best method is to put both handles together and grip around both.
