Kebbit bolts

Kebbit bolts are ammunition used in tandem with the hunters' crossbow. They can be made at level 32 Fletching by using a chisel on a Kebbit spike. Doing so will produce six bolts from every one spike, giving 6 experience each action.

As they are stackable, it may prove beneficial to carry a chisel in the inventory whilst hunting Kebbits, in order to free up inventory space.
