The lower part of the tughra is missing, but what can be read is either the word muzaffar 'Triumphant' which comes after sultans' names in tughras, or Mustafa, possibly Mustafa I (r. 1617-18 and 1622-3).

This is one of a group of rare 17th-century daggers preserved in private aristocratic and museum collections in Germany and Austria and other parts of Central Europe, including Hungary and Poland, which were taken as booty from the defeated Ottoman army at the seige of Vienna in 1683.
