This is for one (1) of the knives shown in the photo. These old Colonial Knives were famous for accepting and holding a razor sharp edge. These are New Old Stock from the estate of a gentleman who used to work for Colonial. They have never been used, carried, cleaned or sharpened. They open and close smoothly with a strong snap. They were stored over the years in a box so some dust, shelf wear and or light corrosion may be found. Super tight in every way. they measure 3.75 inches when closed.
