ED.WUSTHOF knife

[Sparky415]

I found this today, I think its a gentleman's knife with a letter opening blade (sharp with a blunt end ) and a fruit peeling blade? 

On one side of the tang of the long blade
ED.WUSTHOF
SOLINGED
GERMANY

On the other a trident and
ROSTFREI

Etched on the side of the long blade there's a diamond with the initials B then two crossed hammers and the initial  V

On the 'Fruit peeling' blade  (which someone tried to use as a screwdriver    )
the initials D.B.G.M

Anyone have any ideas about it?
