As far as I can see the pommel seems to be hollow and has some kind of rope, cord or string attached to it, but it's somewhat hard to judge from the picture. The "hole" (or whatever it may be) in the pommel gives the impression of some type of maritime implement. My first impression was that the weapon might be of Asian origin, but now I'm not so sure... One strong mental image that comes across is that it could also be some kind of home-made peasant weapon. I don't know from what possible Century it might hail though.
Known measurements:
Length: 138cm.
Width of blade at tip: 8.5cm.
Best regards,
