Used in wood splitting to split with the grain of the wood. Splitting axe bits are more wedge shaped. This shape causes the axe to rend the fibres of the wood apart, without having to cut through them.
The Splitting Axe is one of the more powerful melee weapons and can kill zombies in two hits, or one with a headshot. It can also be used to open cans of food, at the cost of durability and a portion of the food inside. Additionally it can be used to chop down trees to make firewood, and cut up bushes to make sticks. If the condition is low, use stone to sharpen the axe. This will improve the condition by 1 tier.
