- repairing a gun, magazines or bullets
One of the most important crafting actions you do in DayZ is the use of the Weapon Cleaning Kit.
But it is silent.
- repairing a tool
The whetstone is also one of the "all-time used" silent items ingame.
- repairing clothes, backpacks and shoes
Sewing clothes or leather (or using ductape) is quiet, but should it be completely silent?
