Hi ,
picked this up....very similar in hilt design to Tim's example.

The blade does not have a central rib though. It has a flattened diamond shaped profile, nicely tempered, forged with stamped/engraved designs. Steel seems to be good quality showing some age patina......almost certainly early 20th century...but wouldn't be surprised if it was earlier. Blade is approx. 4mm maximum thickness and just over 16" (41 cms) in length.
The hilt has the so called 'skull crusher' pommel , similar to the Tebu daggers, but this has a raised ridge around the edge , both sides (a feature I have not seen before). Handle is plaited/woven leather thonging over fine 'cotton' type material.
The scabbard is leather cored with a thinner leather covering which is hand stitched with braided leather 'detailing'. Four small holes near the throat of the scabbard looks to me that an arm loop was once fitted there, suggesting that this is an arm dagger.
Any ideas gentlemen ......thank you
Regards David
