If you are looking for a mid-sized mallet headed putter then the Odyssey Toulon Portland could well be worth having a look at. As with all putters in the Toulon range, there are deep crosshatch grooves across the entire face of the putter. There is also a small groove inside each of the diamond pattern which helps with the true and consistent roll off of the putter face. The putter head itself is made from a solid block of 303 stainless steel. This is worked and milled by the Odyssey engineers until it becomes the finished product. There is a centre alignment line on top of the face which helps to line up the putter properly.
