# Explain why it's good for the game

Never made sense why they couldn't perform surgery in the first place

Made sure they shared the same capabilities as a glass shard as throwing
knives would be light enough, but not strong enough to break bones like
a standard bayonet would
These things probably don't have sharp edges either, meaning you would
have to hold it awkwardly to perform surgery from the tip
