Interesting comment at etymonline about the boss of a shield. I wondered why armaments were called "sword and buckler".– Andrew Leach ♦Sep 13, 2013 at 8:56

@Andrew@ the OED entry includes "Sometimes wrongly applied to any kind of shield. Also attrib."– Tim LymingtonSep 13, 2013 at 9:27

It’s from Latin buccula, the diminutive of bucca meaning cheek. That’s because a buccula was once the cheek-strap of a helmet.
