Iron Wrench

The Iron Wrench is a tool added by GregTech 4. It serves the same function as the IndustrialCraft 2 Wrench. The Iron Wrench also works as a BuildCraft Wrench.

The Iron Wrench (and other GregTech 4 Wrenches) is also used as a crafting tool to create various items (in most cases, using it in a recipe will take off one durability of the Wrench rather then consume the entire item).
