The sheath is entirely decorated at its drop-shaped tip with spirals, rosettes,
<p>and rhombic appliqués. The upper part displays arabesque leaves and tendrils and the buckle as well as lower tip is decorated with rhombic and rosette-shaped appliqués. The back of the upper part is blank. Thuma daggers were produced only for the Zaydi Muslim elite. They were very precious, and kept in families for generations.
</p><p>On the back of the sheath is an Arabic stamp with the name of the ruler and a date: al-Mansur 115x. The stamp belongs to Imam al-Mansur al-Husayn, who lived from AH 1139 to 1161 (AD 1775-1809).

An engraved inscription in Hebrew names the silversmith: H(arun) Kasil. It is possible that H(arun) Kasil was the same Kasil who lived also under al-Mahdi al-"Abbas, see Walters 57.2319.
