Sawmerang

The Sawmerang is a item in Risk of Rain that fires a sawmerang forward that travels a set distance and then returns to the player, dealing 500% damage and causing a bleed for 4x100% over two seconds. The initial shot and the return trip count as separate attacks, causing the sawmerang to hit twice.

Tactics
Note: This item will always return to you, even if you move higher or lower. Use this to your advantage; i.e., climbing a ladder after throwing it will cause it to shoot upwards as it returns, which may take out aerial enemies in its path.
