Yes, they break locks, people. They can be your best friend and your worst enemy, and can determine the outcome of a battle.

Building

They cost 215 grams of steel to make, and require an anvil in the area you're working in, as well as a hammer in your characters inventory. An anvil has to be built inside, so you'll need to have access to a building.

Use

To break a lock, you simply try to enter into a locked building, and proceed with the picking project. For those that want to help you, they will have to join the picking project initiated by you. This project has a random outcome. Sometimes you break open a lock first try, and other times you are at it for days at end. Each try takes one person about a day.
