Black lacquered hide, 23 1/2” diameter of plain domed form. Four scalloped edge domed iron bosses. The edge with a single hole for hanging. Reverse with original cloth covered hand grips. The knuckle pad lacking. Minor distortion and a little flaking to the surface. About 98% original black lacquer remaining. Worn on the back when riding into battle to protect from the hail of arrows, then brought around to the left arm when the enemy was encountered. The plain edge, rather than the more common upturned, is used as sword technique involved the skilled back stroke or less skilled hack. The thrust in battle was not used until colonial forces were indoctrinated to English tactics in the 18th century. Rare and historic early example.
