Thank you all for your comments, 
Thank's a lot Colin for the pictures, 
i haven't ever seen these models, really look like ! ( just not the crossguard...) 
 
For the sharp edge, yes they are too on both side of the tip , 
Overall except where there is the file-saw 
Interesting the massive 8mm blade that  ends really sharp at edges .( sorry maybe for my bad english ) 
Kind regards
