When playing with 2 or more people, if one player mines and another looks on it will appear to the watching player that the miner is breaking the block with their fist and that the tool is suspended at their side, from the miner's first person view, everything looks normal, I have tested with pickaxes and shovels so far on survival, also happens when using 3rd person view from the front as seen in the screenshot
