Black hatchet
From Emps-World Wiki
The Black hatchet requires an Attack level of 10 to be equiped. It can only be purchased for 472 coins in Bob's Axes shop located in Lumbridge and Port Sarim. The Black hatchet is usually only used for the Woodcutting skill; a Woodcutting level of 6 is required to be able to cut logs with it.
Hatchets can be used from your inventory to cut wood with, if the player does not have the required Attack level to equip it.
