Kard (Persian: کرد ) daggers are characterized by having fairly straight thrusting blades, some with extra reinforcement at the tip, to strengthen this piece for stabbing through heavier protection. When sheathed, most of the handle goes into the scabbard.
Such daggers are found in most of the Islamic world, from Ottoman Turkey to the Caucasus, into old Persia, Sindh, and North India.
Most kard seem to date from the 18th century and before. Some of the finest examples were made in Persia. The better examples have wootz steel blades, hilts of precious materials and fine chiseled decoration.
