The pitones
Copied on the Spanish sword guards of the late 15th and early 16th century, the pitones equip the Hispano-Moorish nimchas . This type of device, which never existed in Spain, is found on very rare ancient examples of Moroccan nimchas and never on Arab sayfs. Ref .: Museum Real Arméria of Madrid, Museum of Batha in Fez and work of Charles Buttin.
(While I was constructing this frame I was also inspired to do a thread on Quilons on ethnographic since there are widely ranging aspects to that part of the sword and occasionally dagger.)
(I add the Tulvar out of interest since this is not only a decorative or functional extension of the hilt forward of the guard but a type of breakwater device to entrap a sliding blade.)
