Hammer axe

[Daubee]

I knew this man of Torvaldsland only by reputation. He was a rover, a great captain, a pirate, a trader, a warrior. It had been he, and his men, who had freed Chenbar of Tyros, the Sea Sleen, from a dungeon in Port Kar, breaking through to him, shattering his chains with the blunt hammer like backs of their great, curved, single-bladed axes. He was said to be fearless, and mighty, swift with sword and axe, fond of jokes, a deep drinker, a master of pretty wenches, and a madman. But he had taken in fee from Chenbar Chenbar’s weight in the sapphires of Shendi. I did not think him too mad.”
