The slightly yataghan blade is 565 millimeters long and has wide unstopped fullers.

Albert N. Hardin, The American Bayonet 1776/1964, #113

The unique features of this arm are the horn grip and the internally sprung stud-lock mechanism.

The slender, slightly yataghan patterned blade with wide unstopped fullers is 22.25 inches (565 mm) long, 1.03125 inches (26.2 mm) wide and .28125 inch (7.1 mm) thick.  The blade is unmarked and bears evidence of having originally been blued.

The hilt is 4.8125 inches (122 mm) long.  The guard and pommel are of cast brass, and the grip is laminated and covered with translucent horn.  The lower guard terminates in a forward curving finial without the internal disk detail.  The upper guard, whose surfaces are slightly oval, has a  .891 inch (22.6 mm) diameter bore.  The smoothly polished horn grip is held to the tang by two large transvers steel rivets.  These are peened and filed flush with the grip.  The lower surface evidences two vertical wafers of of non metallic material set in along the central axis.  The wide flat backstrap is stamped midway in horizontally inverted characters: convexly arched "PAT'D" / "1960" over concavely arched "MARCH 6".  The pommel has a square-backed bird's head with a sharply subdued beak.  The wide, moderately deep stud groove appears to be hand filed and has a taper along the upper surface.  It runs up to the horn grip.  The location of the internal spring to the stud lock defies detection.  The pommel is held in place by two transverse steel pins, one below the stud lock and the other through the beak extension.

Is it made by or for the Confederates?  Hardin did not comment on the issue and the patent date is clearly before the war began.  I doubt a southern manufacturer would have honored a northern patent.  It could have been made and sold to a southern state militia before the war started.  Jim Maddox has it classified as Confederate so for now it will be listed as Confederate until proven otherwise.
