The Luna is a putter developed by five-time world champion Paul McBeth. It feels extremely good in the hand thanks to the soft plastic and can be used by anyone, from players who have just started to the six-time world champion. The putter is mostly used for putting and rarely thrown from the tee.
It is a slightly overstable putter that becomes more neutral fairly quickly as the soft plastic keeps hitting chains. That does not make it any harder to putt with, even once it is a little worn.
