Likely manufactured in the mid-19th century, Manson was one of many firms located in Sheffield, England that produced knives intended for the booming American market around and during the Civil War. It measures 10 1/2 inches overall with a 6 3/8 inch clip point blade with American patriotic etching on the left featuring "O.K." and the slogan "Americans ask for nothing but what is right and will submit to nothing wrong" in two blocks. The left ricasso is marked "MANSON/SHEFFIELD". It has a German silver oval guard ("KO21" collection marked in removable black paint) and coffin shaped pommel with a lion couchant, and it is fitted with checkered hardwood grips. Includes a lightly tooled leather wrapped scabbard with German silver fittings.

Fine overall, the blade mostly bright with some scattered light pitting and mostly well-defined etching. The German silver shows an attractive, lightly aged patina overall and the grip scales show minimal handling evidence. The scabbard is also fine with some moderate wear on the leather.
