what kind of knife is this...?
 

just bought this knife, filigree silver, 8.25 inch / 21 cm
the seller's description was :

- antique knife filigree Russia or Ottoman
- circa late 19th early 20th century.
- no marks but Filigree tests silver . Probably 800 something
- not sure what it was for ? Possibly a paper knife but it’s surprisingly sharp.

I think that it is not a paper knife and thought more of a fish filleting knife, but than again...such a knife does not need to be sharp...
and for a butter knife the blade might be too short....?
Agewise it might indeed be 19th, 20th century

Russian I doubt as well as there certainly would have been a zolotniki silvergrade and maker's mark.

The filigree does look like Mediterranean to me and would also explain the absence of any mark...

Any of you know got any idea where it comes from, recognizes it or does know what kind of knife it is ?
Your reply will be highly appreciated!☼☺☼

almost 2000 hits and no one has any clue...?
Guess we're all ...

It's a fancy 19c butter knife.

Thank you very much !

Another possibility is a fish knife. Fish knves and forks for formal eating of fish had a similar blade shape, and there was a larger version used to cut and serve fish. Given that the blade on the knife in question is sharp, then I think a fish serving knife may be the most likely use for it. Butter knives are notoriously blunt because butter at room temperature is very soft.


Here is a set of a fish knife and fork for serving.

I agree with Ian, it's a Fish Slice serving tableware.
