Bark

Bark is a resource that can be obtained from trees.

It's mainly useful as a crafting material.

Bark can also be equipped and used, which will randomly produce slime or insect parts. A single piece of bark can be used in this way repeatedly, but it will eventually break.

You can also start a fire by combining a piece of bark with a branch near a campfire. However, this won't always work. A pair of flints is a more reliable way to start a fire.
