I switched from a hammer grip atlatl to a split-finger grip atlatl after injuring my wrist. At the time I was throwing darts every Tuesday with the
Tyoga Atlatl Association. I couldn't throw with the hammer grip atlatl I was using and not wanting to stop I tried a
Basketmaker atlatl I had laying around. The different style of throwing split-finger atlatls had no effect on the injury I had. My average weekly score actually increased. I've been using the Chemung ever since.
