The adamant axe is an item mostly used in the skill Woodcutting. Using this axe requires level 31 Woodcutting. Level 30 Attack is required to equip it. It can be made by players with level 71 Smithing. As with all axes, carrying one in the inventory along with the necessary Woodcutting level will work. In terms of its Woodcutting speed, the adamant axe is currently the fifth most efficient axe in the game, just behind the rune axe, dragon axe, the infernal axe, and the 3rd age axe.
