A dolphin hammer is one that has been shaped and engraved to resemble the sinuous form of a swimming dolphin. I think the jury is out as to whether there's a significance or symbolism to the form, or whether it was just a pleasing form that became popular. Pineapple finials are another form you'll see on a lot of muzzle loaders, less so breech loaders.
