Cheese Knife Agate Handle Natural Stone Souvenir

Approximately 17cm in total length.

I believe it's a cheese knife, but I apologize for not being knowledgeable about the blade shape or other details!
The handle is made of pale blue agate.
The blade also feels quite sharp to the touch. Perhaps it's a tool for carving like a chisel?

How about for bartenders, chefs doing live cooking, or for performance use?
