The Tool workshop is a new building in the NPC Village. It has a "carpet" of 3x3 white wool. It also has several useful features, including: 2 Stencil Tables, 2 Part Builders, 2 Tool Stations, 2 Pattern Chests with various Patterns, 2 Pistons, and 2 Chests with various tool parts. This last feature is very useful to those beginning a new world, as it allows the creation of relatively high-level tools (Iron, Copper, Bronze, Obsidian) very soon after creating a new world. It also has a ladder leading up to the roof and no torches, thus causing villagers to avoid it because mobs can spawn. It often spawns with its door below the surface of the gravel road. This is likely a bug.
