Christofle Butter Knife, Mini Size, 9.5cm, Set of 2

This is a mini butter knife from Christofle, a renowned French brand.
It is a discontinued item and is said to be a rare piece with a unique groove design. There is also a flat type with the same form.
I bought it at an antique shop in Nagoya (I forget the name) along with a small Baccarat plate, but I'm not sure if it falls within the antique category.
It's small and cute. Just looking at it is enchanting.

- Brand: Christofle
- Size: 9.5cm length
- Quantity: 2 pieces
