The little grater for condiment is made out of copper by a Japanese old manufacture. It is a single-face grater that doesn't separate the fiber from the juice to preserve all the flavors. It is traditionally used for ginger, wasabi root, garlic and citrus zests.
The very sharp blades, voluntarily irregular are made one by one by precise hammer strokes on the copper surface. Long lasting and antibacterial, copper is the perfect material for kitchenwares.
This grater, identified since 1712 ( Edo era encyclopedia ) is part of Japanese kitchen treasuries.
It is a purely aesthetic variation, the turtle is a symbol of longevity : "mannen" ( 10 000 years )
