The Blueprint Manager is an item found in a player's inventory, which contains all purchased blueprints of a player, and cannot be dropped or lost upon a player's death, unlike axes. The player will get this item after they have bought their first blueprint.
The Blueprint Manager is a blue sheet of paper rolled up with mathematical drawings on it, much similar to a real life blueprint. When you open the Blueprint Manager, there is a large text that reads; "Blueprints", and underneath that, you can see the blueprints that you have purchased. Previously, it was impossible to organize blueprints bought in a specific order. However, on September 25, 2016 Defaultio released a Builder's Update. The blueprints will be in the order in which you bought them, as well as categorized by their classification on the tabs to the left of the screen.

On the left side of the Blueprint Manager, you will see the various categories (in order):
*NOTE*: In order to use blueprints, you must have land to place the blueprints on.
