The Royal Marine Sword is influenced by the Infantry Sword pattern of 1897. The straight carbon steel blade of this sword is two-edged for the final section of its length. The crest of the Royal Marines is also engraved on the blade. Blades can be procured in nickel plating as well. The nickel plated guard is a three-quarter basket hilt, pierced and etched with a scroll pattern that incorporates the royal cypher of the current sovereign.

The grip is in black fish-skin normally shark skin with a silver-plated copper wire wrapped in a spiral around it.

The Royal Marines Sword is carried in a Sam Browne leather scabbard with plated steel throat piece for service wear and for full dress occasions.
