Underwater hockey stick evolution - Underwater hockey is a pool sport. It is like Ice hockey but under the water. In addition to the stick and puck; equipment needed are fins, snorkel, mask and glove. When I began playing about 7 years ago, we played with the clunky ones on the left of the puck. I cnc routed the shapes from high density polyethylene. This is a work in progress, as the current sticks on the far right are still not great, but they are far better than the mallets we started with!
