A screwdriver is a one-handed, short blade weapon and a useful tool.

Usage

Tool

If a screwdriver, saw, and hammer are in the player's inventory, a player can dismantle player-made objects (water barrels, crates, etc) and world objects (complex furniture, metal security doors, etc). When disassembling player-made objects, some of the materials that went into making an item will be returned to the player's inventory upon successfully dismantling it. The screwdriver is also needed to change attachments on firearms (suppressors, sights, chokes, etc).

The screwdriver is also needed to disassemble electrical devices, such as radios and digital watches. It is also used to create improvised electronic devices, such as timers and triggers. It is also needed to remove headlights, taillights, and the radio from vehicles.

Weapon

In times of emergency the screwdriver can be used to quickly take out small groups of zombies, but it is unfit for hordes.

It has low durability and damage, requiring many well-placed hits to kill a single undead. However, it can perform jaw stab attacks.

The screwdriver cannot be repaired, which makes it useless once broken.

Condition

The screwdriver has a maximum condition of 10. Its rate of degradation is influenced by the short blade and maintenance skills. The chance of losing durability can be simplified to the following formula: 1 in (6 + maintenanceMod × 2). Where "maintenanceMod" is calculated using the short blade and maintenance skills.
Below is an example of the chance of losing durability at varying levels of the maintenance and short blade skills.

*For how this is calculated, see: Condition*
Maintenance skill	Weapon skill	Condition lower chance
0	0	1/6 (17%)
0	4	1/8 (13%)
0	8	1/10 (10%)
4	0	1/10 (10%)
8	0	1/14 (7%)
4	4	1/12 (8%)
4	8	1/14 (7%)
8	8	1/18 (6%)
10	10	1/20 (5%)

Distribution

The loot distributions can be found in the table(s) below.

Screwdriver distribution Show / Hide

Effective chance calculations are based off of default loot settings, and median zombie density. The higher the density of zombies in an area, the higher the effective chance of an item spawning. Chance is also influenced by the lucky and unlucky traits.
