This registers a hammer with the name “My Cool Hammer” that has the ID `mymod:my_cool_id`. The head base texture is `mymod_my_cool_texture.png` and the texture is automatically masked to form a hammer head.
If instead of `head` the value `texture` is provided then the automatic texture generation is disabled and the hammer will get the texture defined by the `texture` value. If both values are added then the `texture` value is given precedence.
The hammer is crafted like the provided hammers with two sticks and two of the items provided for `craft`. The hammer is crafted like the provided hammers with two sticks and two of the items provided for `craft`.
`uses` defines how often the hammer can be used. The value also gets stored in the tool’s definition as `_uniham.uses` that can be used by a custom `on_use` function for example `uses` defines how often the hammer can be used.
