The octagon handles are excellent. One of those great old ideas that has all but disappeared. I've always found it less fatiguing over the long haul. Somehow the octagon shape is easier to grip, Wish some of the modern hammers would try that shape.
But I wish there was more material left on the head. There is a lot of variation in the eyes of old hammers. And unfortunately mine is a bit larger than the octagon handle so I'm going to have to do some creative wedging.
