Why did the Germanics used pointy shieldbosses?

[Conal]

It may have started with ease of manufacture. A semi circle will form a cone which can them be welded to a band to fix it to the shield. I vaguely recall reading that somewhere???

I was under the impression that it was the Migration period shields which had this and they were the smaller round shields or smaller oval ones rather than those big old convexed ovals. This would make sense when considering the boss as an offensive weapon to injure as much as protect.
