Tough Rod

The Tough Rod is an item added by Tinkers' Construct which is used in advanced tools and weaponry. It costs 3 ingots worth of a material to create. For example, if the player were to make an Iron Tough Rod, it would require a Smeltery, a Tough Rod Cast, and 3 ingots worth of Molten Iron.

Usage
Tough Rods are used to make the following tools and weaponry, most of which require a Tool Forge to be created:
 * Hammers
 * Lumberaxes
 * Excavators
 * Scythes
 * Cleavers
 * Battleaxes
 * Javelins.

Javelins are the only weapon that can be crafted without a tool forge.
