Sheffield Cutlery Mother of Pearl Handled Knives

This is a boxed set of Sheffield cutlery stainless knives with genuine mother of pearl handles. I am not sure of the correct name to call them, they are little knives.They were made in England and sold by Kirk & Matz in the USA. It comes with original box and tag. I will date these pre-1970s. This set appears never to have been used.The knives are in excellent condition.The box is in very good condition with slight fraying on corners. Knife size: 4-7/8” x ½” Box size: 6-3/4” x 3-1/4” x 1”
