Knife

A Knife is a tool used for a large variety of tasks, mostly for making logs into bows using the Fletching skill. This is also an excellent tool for cutting through webs, especially to the Mage Arena in the deep wilderness. Knives can be bought in the Catherby general store and found on a table in the Musa Point general store. There was a notorious glitch involving knives in RuneScape Classic.

Trivia

 * In the early days of RS Classic, free players could pick up a knife and throw it.
 * The Knife bug in Runescape Classic had a glitch which allowed players to wield a knife, giving very high strength bonuses that made players with level 1 Strength hit in the 10s (10-20). This glitch was later fixed.
 * Sometimes in RuneScape HD, when you click the knife, it looks like an item before you wield it, yet nothing happens.
