Stick Variants

For various purposes, the typical wooden stick has multiple variants.

Rebar
Rebar ("reinforcing bar") is an iron-based stick variant. Currently, its only use is to craft Obsidian, Soft Bedrock, and Mithril tools. They are crafted by putting Iron Ingots in the same pattern you'd use to make sticks with wooden planks, which gives 2 Rebar.

Blaze Rods
Blaze Rods, dropped by Blazes, are used to craft Eterna tools in the place of sticks.

Obsidian Poles
Obsidian poles are an obsidian-based stick variant. Currently, its only use is to craft Adamantium tools. Like Rebar, its crafting recipe is simply two Obsidian in the same pattern you'd use to make sticks, which gives 4 Obsidian Poles.
