Skull head romantique stiletto
 

Maybe will I have more success with this small stiletto dagger:

Uncleaned and made of steel,
the tip is broken and it is 25cm long.

A romantic Victorian model ?

Going by the visable casting lines, I'd estimate it to be closer to the 1970s than 1800s.

Thank you Radboud,

Yes the hilt is cast,
I saw old ones with cast hilt too
The blade sounds good when I touch it ,
I will clean it and see how is the steel under...

Masonic ???

good call
 

Hi Jim. Yes, I suspect so too.

Thanks Keith,
seems like the daggers usually had crossed bones guards. This skull and crossbones theme is pretty well known in Masonic regalia and has to do with the omenous 'memento mori'.

this sword is a great example of this kind of Masonic symbolism, and was mounted on a Napoleonic cavalry blade, wish I would have got it! Pretty spooky :)
