Wilson 8802 putter

“Woods also didn't have a bag during the session, but instead was seen using just a small selection of clubs - three wedges, a 9-iron, an 8-iron, his Scotty Cameron putter, and, most intriguingly, a Wilson 8802 blade putter.”

“The putter is similar in design to the popular Wilson 8802 blade model that Mickelson has used throughout his career.”

“he pulled out an old Wilson 8802 with a “fluted” shaft to practice with to create that “release” he was looking for”
