Not so long ago I was able to add this dagger to my collection, in this thread:
http://www.vikingsword.com/vb/showth...light=ligurian were shown similar daggers so I think that it could be a Ligurian dagger. It's 33 cm (13") long with a blade from 20,6 cm (8-1/8"). Am I correct? Any age guess? All other comments are very welcome.
