In France it used to be quite popular to have knife rests at a dinner table.
I am not sure of what metal they are made.
Size of one:
length:9cm (3.5 inches)
hieght:2.5cm (1 inch)
They are in medium to good condition. One has a dark knock on the cross back and a slight bend on one side but still stands fine.
PLEASE NOTE: They look lighter in the photos then they really are.
Please note that I ship from France so shipping times are longer.
