Collins and Co. made the saber bayonets, the problem with them was that each one was hand fitted to a specific rifle, so the serial number on the Collins bayonet matched the serial number on the Plymouth rifle it was fitted for. They were not interchangeable, if either the bayonet or rifle was damaged or lost, its counterpart was useless.
The Dahlgren "Bowie" bayonet solved that problem. They were interchangeable, and much more practical as a bayonet. But they were short enough to be used as fighting knife as well. The actual use of either was probably minute at best, except maybe by the occasional naval shore party. The most advantageous use of the bayonet would have been to repel boarders, of which the Saber bayonet would have worked best, as it could also be used as a short sword.
