Produced at an unknown date, hard information on "Dufilho" is very scarce; William Albaugh III's "Confederate Edged Weapons" places him as active in New Orleans during the Civil War, with recorded specimens of Confederate swords of style and quality sufficient for officers that appeared to use the same etcher as noted CSA arms supplier Thomas Griswold & Company. Measuring 6 1/2 inches overall, the dagger is fitted with a 3 5/8 inch long double edged spear point blade, which is hollow ground in a diamond profile with a ricasso marked with a stylized arrow point on one side and "DUFILHO/N.ORLEANS" on the reverse. The grip is smooth one-piece antique ivory, 3 inches long with an oval profile, flat sides and a German silver ferrule for the blade tang. The tang is German silver construction, with a small frog stud on one side. While the identity of the original user of this knife is lost to time, push daggers were one of the signature weapons of the riverboat gambler, being more concealable than a traditional bowie knife and handy in a tight spot, and New Orleans, prime destination for boats headed down the Mississippi, an ideal place to pick one up.
