Question

Where is the "butt " of the club as one of the answers says use as a guide?

Answer 1

The butt of the club is the end of the shaft furthes away from the head. It is the end of the grip.

Answer 2

The butt was properly explained as the end of the shaft furthest from the head of the club. There is no reason for using this as a guide unless you "plum bob " to determine if there is a slope or curve on the green.. In 70 + years of playing this game I have yet to see the benefits of the procedure.
