The Your Eternal Reward is a user-made promotional in the game Team Fortress 2. It is used by the Spy and replaces the default Knife.

This knife, upon a successful kill, will make the enemy's body disappear, along with the victim staying silent when killed. This also puts you in disguise as the victim. If you kill them via Backstab, there will be no kill report on the screen.

The downside to using this knife is, due to the disguise effect, your cloak is disabled.
