Bistrom's Greataxe is a weapon of achievement and two-handed axe for players who have level 100 Woodcutting. It is an achievement to wield around, and can be used as a weapon.
The only way to receive Bistrom's Greataxe is to buy it off Bistrom Choppa in the Woodcutting Guild at 100 Woodcutting for 100
The ability known as Power Chop, deals two quick strikes to the target.
If the ability is used on trees, it fills your bags fully with wood.
This requires 100% of the adrenaline bar, and 100 hits to replenish.
On Godwood trees, this will give only 10.
