The Chain Knife attacking a Target Dummy. Note how the Knife immediately returns when hitting a block.

The Chain Knife is a pre-Hardmode flail that throws a knife-like projectile attached to a chain. It only extends a short distance of 9.4 tiles, though its quick use time and velocity may make it a good early to mid-game weapon. It has a 1/250 (0.4%) chance of being dropped by a Cave Bat.

Its best modifier is Godly or Demonic. Both modifiers increase the average damage output by the same amount. However, Ruthless might be preferred if the player already has very high critical strike chance.

Notes

In Don't dig up and Get fixed boi seeds, the Chain Knife receives the following changes:
- Switched place with KO Cannon. As a result, it is dropped by Clowns instead of Cave Bats.
- Damage increased from 12 to 60.
- Use time decreased from 20 to 15.
- Value increased from 1 GC25 SC to 17 GC50 SC.
- Maximum range doubled from 9.4 tiles to 18.8 tiles.

Tips

It is good at killing quick flying enemies. It is also good at killing large groups of Wall Creepers, and keeping the second form of the Brain of Cthulhu at bay.
A Bat Statue can be used to easily farm bats to obtain the Chain Knife. Note that drop rates from statue enemies are reduced by a factor of 5.
- If the player finds a Bat Statue Underground before defeating Skeletron, they can put in onto a Wire (in between a trap and its Pressure Plate) and step on the Pressure Plate to make a crude way of spawning more Cave Bats.
Although the weapon attacks quite quickly, it is very difficult to stunlock enemies with it due to its low knockback.
