The hilt could be Dutch or French, the use of tortoiseshell having been introduced to Europe in the late 17th century, probably through Dutch colonial connections. The mid 18th-century German blade (26" long) would have replaced an earlier, shorter, straight, double-edged blade (broken?), probably to enable the weapon's use as a naval hanger.

This hanger, almost certainly of military or naval origin, is an exceptionally clean example with a 24" sawback blade and a staghorn grip. Typically they would have been used in the Seven Years War, as well as in the US War of Independence. It would have been carried in a brass-mounted leather scabbard, now sadly lacking.

This is likely to have been made towards the end of the American Revolutionary War (Peace of Paris, 1783) or during the early part of the Napoleonic Wars (starting 1793). This would have been carried by an RN officer or HEIC naval officer, and this example is interesting in having a particularly long (approx 26") blade.

This is a typical 18th-century Spanish weapon, designed to be stuffed down a musket barrel when out on a boar hunt or in a military context. Amazingly, it appears to have most of the original scabbard, with the top chape of pressed tin with a decorative motif. The bottom chape is missing.

This is the SA dirk 1933 pattern, modified with a black finish to the scabbard by order of Korpsfuhrer Huhnlein in 1936. The RZM code stands for the firm Lauterjung & Co of Solingen. The top chape is engraved '15/24547' for Standarte 15, part of Nordmark Motorgruppe at Itzehoe, with the owner's personal NSKK number.
