Beruel's Retort +1 is an enchanted throwing axe, although the item description fails to note this. As such, it can be either wielded in melee or thrown as a missile, with +1 bonuses to damage and THAC0 from the base statistics given for a throwing axe.
In-game description Edit
|“||The only thing dwarven warriors love more than a cool pint of ale is a short-hafted blade of cold steel. Perfect for penetrating the thick skulls of orcs, these axes serve equally well when thrown or held in one hand.||”|
