Knives are a weapon usable in the game Shadow Fight. They add 30% of power to your attacks. They are relatively strong for an early weapon, but don't have the reach that batons do, and require at least 400 Tourney, rating in order to buy. They cost 250 gold in order to buy.
It is also one of the weapons that can be used to fight Div. If he is defeated, he will lose 10 HP.
