One example of a mace capable of penetrating armour is the flanged mace. The flanges allow it to dent or penetrate thick armour. Flange maces did not become popular until after knobbed maces. Although there are some references to flanged maces (bardoukion) as early as the Byzantine Empire c. 900[2] it is commonly accepted that the flanged mace did not become popular in Europe until the 12th century, when it was concurrently developed in Russia and Mid-west Asia.[citation needed]
