The Wrench is a default tool in Blockland.
Blockland 03106

A blockhead eventing a 2x2 brick with the Wrench.

It spawns by default in Player's inventory.

It is used for editing the properties of bricks, which include items, emitters, lights, events, music, and naming, which is used in eventing. It can also be used to make bricks invisible (called rendering), allow projectiles and vehicles to pass through it (called raycasting) or allow players to go through them (called collision.)


This is what pops up when you wrench a brick.
