Callaway Odyssey Ai-Dual One Putter

A crank hosel is the shape most people picture on a classic blade, bending forward off the heel and back again to set the head behind the shaft. On the Ai-Dual One it produces slight toe hang, so there's a little arc built into the stroke it expects. Blade head, three lengths, black, both hands.

Blades are where insert technology gets argued about hardest, because a golfer choosing this shape is often the one who wants feedback from the face rather than protection from it. Odyssey's answer is a two-layer insert, soft on the outside and firm underneath. It won't feel like cut steel. What it will do is take the click out of the strike without turning the whole thing to mush, and the crank hosel keeps the offset that a blade player expects to see.
