Price reduction. Sashimi knife?

This item was received from a child.
It looks like a kitchen knife, but I'm not sure.
It also looks like a sashimi knife.
It has a sharp blade.
This is a listing for two items together.
There was no handle.
Therefore, I believe it is unused.
The material appears to be iron as it reacts to magnets.
There is currently no rust.
