The Mamluk dynasty existed from approximately 1250 to 1500 A.D. The Mamluks were slave soldiers from Central Asia who earned their freedom and became rulers of a dynasty which lasted 250 years. Their rulers were known for patonage of the arts, thus this was the most prolific and influential period for Islamic art. Mamluk metalware is recognizeable by the repeated cartouches and medallions and the chain patterns encircling the pieces. There was a revival of this style of art spurred on by wealthy travelers who went "on tour" for extended periods of time.
This This knife features a graceful curving line, with intricate etchings, and jeweled accents. Measuring 17" (43cm) long and weighing 1 1/4 pounds (.57kg), the handle and sheath are faced with with etched white metal and the back is in brass. The blade appears to be carbon steel, and isn't particularly sharp. There are a pair of rings for attaching it to a belt. I suspect this may be a Moroccan ceremonial or display piece from the 1950's.
