A straight shaft putter, on the other hand, is exactly what it seems: the shaft goes directly to the putter and the putter's face is aligned with the shaft. Traditional wisdom holds that mastery of the eyes should dictate whether you need a balanced putter. If your main eye is dominant (left eye for right-handed golfers) then you should go with a straight shaft putter. If it's your final eye, look for a medium or full scroll.
