Dirk, which belonged to Admiral David Thomas Norris (1875-1937). The hilt of the dirk consists of a gilt cross-guard with acorn terminals. On the obverse side at the centre of the guard is an oval plaque decorated with a crown and anchor badge, surrounded by a laurel wreath. On the reverse side at the centre of the guard is a gilt button for releasing the dog-catch, which engages the throat of the scabbard. The dirk has a gilt lion's-head pommel and back-piece, the mane extending to the straightened ferrule at the top of the grip. There is a ring in the lion's mouth to take a dirk knot, which is now missing. The white fish-skin grip is bound with three gilt wires.

The steel blade is a straight, flat-backed with a pseudo false edge and a symmetrical point. The blade is engraved for most of its length. The obverse of the blade is engraved with a rectangle containing five oval designs, entwined foliage, a foul anchor with a crown above surmounted by rays, and further entwined foliage. The reverse of the blade is engraved with a rectangle containing five oval designs, on a smooth ground, entwined foliage, Queen Victoria's cypher surmounted by her crown with rays above, and further entwined foliage. The black leather scabbard has a gilt top locket, which is fitted on each side with a gilt ring for suspension and a gilt chape. The gilt parts are decorated with groups of horizontal lines. Although this dirk is of the 1879 pattern, it can be dated more closely by reference to the maker, Seagrove & Company who operated under that name at The Hard, Portsea, Portsmouth, from 1892-1903.

Admiral David Thomas Norris (1875-1937) became a Midshipman at the end of 1891, so it seems likely that he purchased the dirk early the following year. It was also likely that the firm was in operation under their new name Seagrove & Co., before 1892 for a short time. Admiral David Thomas Norris (1875-1937) entered the Royal Navy in 1889 and became a Midshipman in 1891. He was promoted to the rank of Lieutenant in 1896; to Commander in 1907; to Captain in 1914; to Rear-Admiral in 1924; to Vice-Admiral in 1929 and to Admiral in 1933. He died in 1937.
