Only 1,002 Model 1880 knives were manufactured in total, with this example constructed in the early style configuration with an iron guard. It measures 13 5/8 inches overall, with an 8 1/2 inch single edged blade set in an iron guard marked with "U.S./SPRINGFIELD" on the left and serial number "113" on the right. The ribbed wood grip has "S.W.P./1881" stamped on the butt, the initials of Springfield Master Armorer Samuel W. Porter. Includes a brown leather sheath with Watervliet Arsenal maker marking, fitted with a brass throat and a belt loop with hinged cartridge loop bar marked "R.I.A" for Rock Island Arsenal.

Very good, blade and guard showing mostly a bright gray patina with some scattered patches of dark brown colored light surface pitting. The wood grip is also very good with some scattered light handling marks, and well-defined serrations. The sheath is fine with light wear, some light age cracking, and attractive golden aged patina on the brass.
