In-game description

The whetstone, or sharpening stone, is a tool used to sharpen bladed tools.

Overview Edit

The whetstone weighs a mere 0.10 kilograms and can be found in containers and buildings likely to contain tools. It is always found in 100% condition. It is known to spawn in Quonset Gas Station and Barns.

Use Edit

The whetstone is used in the bladed tool maintenance gameplay mechanic, to restore the condition of the hunting knife and hatchet. It is not a permanent solution and at some point a hand-made alternative will be needed.[1] Each use degrades the whetstone 5% (20 max uses) but restores less than this in the target tool.

 Sharpening Edit

As of version 0.393, the Sharpening skill, which is only visible when maintaining a bladed tool and not in the player's journal, starts at 30 points for the player. The skill point increases by 1 for each time the blade is sharpened. Skill progression bonus are detailed below:
