Bearing the mark of "ARNOULD/NAMUR", a Belgian cutler active in the 19th century also known for making veterinary/medical multi-tools, on the left side of the blade, this knife measures 9 1/4 inches when closed, the edge of the blade nesting into a fixed spine and the grip assembly, and the spine of the blade rests flush against the handguard. A thumb lever on the left side of the guard holds the blade closed against spring tension, and when depressed the blade snaps out and engages a lock-back retention mechanism, for a blade length of 8 1/2 inches and an overall length of 17 3/4 inches. The guard is steel construction, with a set of smooth antique ivory grip panels.

Very good overall, with some minor spotting and a few areas of pitting on the steel and an attractive aged color, visible grain, and a few age splits in the grips. The retention mechanisms are in good working order, and the spring retains good tension.
