What does buckler mean?
A buckler is a small, typically round shield, usually about the size of a dinner plate, held by a central handle on the back or strapped to the forearm. Unlike larger shields such as the kite or heater shield, the buckler was designed for agility: it was light enough to be maneuvered quickly to parry blows, catch an opponent's blade, or punch in close-quarters fighting, making it a favored companion to the sword among medieval infantrymen and Renaissance duelists. The phrase 'sword and buckler' became so entrenched that it described an entire style of fencing practiced across Europe for centuries. By extension, writers have used 'buckler' figuratively to mean any source of protection or defense, echoing its appearance in older religious and literary texts. Today the word survives mainly in historical, martial-arts, and literary contexts, lending any sentence a distinctly archaic, armored flavor.

Etymology of buckler
'Buckler' entered Middle English around the thirteenth century from Old French 'bocler' or 'boucler', meaning a shield with a boss or protuberance. The French term derives from 'bocle', the boss at a shield's center, which traces back to Latin 'buccula', a diminutive of 'bucca', meaning 'cheek'. The same Latin root gave English 'buckle' and 'bouclé', all sharing the sense of something rounded or swelling outward like a cheek.
