A prybar can be used to open locked containers, such as lockers and car trunks (they cannot be used to open Cargo containers). It is additionally used to break the ice on ice-fishing holes, and as a weapon during Struggles. They cannot be repaired but can be harvested for some scrap metal. Prybars are fairly common and can be found in almost any condition. It's one of the most important early game gear allowing you to open locked containers which usually have better gear.
The Prybar cannot be manually ‘equipped’ as a weapon like the bow or rifle, and it cannot be used as a weapon outside of a scripted event. Only certain items can be used as weapons in struggles. The hatchet is the most effective. The Prybar will lose condition if it is used in a struggle.
Like the Heavy Hammer, the Prybar counts as a "scare" or "blunt" weapon, having less damage and less chance to scare a wolf than the Heavy Hammer.
