A firm grip on the handle as the axe hits the wood is a sure way to sore/strained wrists even for a normal axe, as the handle can rotate and also vibrate, depending on how and where it hits the wood. A loose grip looks like a must with this axe. Notice the handle is round for most of its length, to rotate easily. This is not usual for a normal axe, as the shape of the handle gives position feedback to the hands.
