Thank you for your interest in this excellent condition knife from The Brian Sorenson (Ivoryman) Knife Collection. This Northfield Eureka Jack #922219 pattern knife is manufactured by GEC and is 3.875" long and comes with the original white tube with printed label. The antique goldenrod camel bone covers, limited to 702 knives, are without chips or cracks. The unsharpened and unused long pull matchstrike spear point main blade and coping secondary blade have a solid half stop and snap firmly when opened and closed with zero side-to-side play when fully extended. The forced patina on the blades was done by Ivoryman for both aesthetics and preservation and there are several methods that can be used to remove it with varying levels of abrasiveness and ease if desired. The brass pins and liners and nickel silver double lined bolsters and shield are in commensurate condition with the grade of this knife.

Keep your edge sharp, otherwise you just can't cut it.

That's gotta be one of the best examples of Ivoryman's signature cool blue patina
