Engineering Workbench
This allows you to craft and unlock electrical, water and industrial items
The Engineering Workbench is a workbench in Rust with 500 health. You craft it at a Level 1 Workbench, and its blueprint costs 100 scrap to research.
About the Engineering Workbench
Experimenting at it costs 75 scrap and teaches a random blueprint you do not know yet, out of 94 on its list. It has 10 slots for workbench upgrades such as the Accelerated Workbench Upgrade, Comfort Workbench Upgrade and 8 more.
Outside a tool cupboard's range it holds for 2 days, then decays from full health to nothing in 4 days.
On the tech tree it sits behind one other unlock, the Salvaged Hammer. In all, 23 loot sources drop it; the full list of where it drops gives the chance for each.

A full repair at a Repair Bench costs 101 × Wood and 21 × Metal Fragments, and you need its blueprint.

A green recycler always gives back 250 × Wood and 50 × Metal Fragments for one.

Blueprints it can teach
Experimenting at this bench teaches one of these at random, each time a blueprint you do not know yet. On the tech tree each one costs what Alone says by itself, and With its path from scratch, the blueprints before it included.
