Knife

A knife is a tool used for a large variety of tasks, including 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, the Shantay Pass Shop, from Jofridr Mordstatter inside the bank in Neitiznot, and from Polypore Dungeon Supplies as well as having respawns on a table in the Musa Point general store, in a house behind the bank in Catherby, behind the axe shop in Lumbridge and on a table in Lumbridge Castle's cellar. Knives can be stored in the Toolbelt.

Trivia

 * The current appearance of the item's inventory sprite resembles that of real-world Bowie knives.
 * In the early days of RuneScape Classic, free players could pick up a knife and throw it.
 * The equipable knife glitch in RuneScape Classic allowed players to wield a knife, giving very high strength bonuses that made players with level 1 Strength able to hit 10-20 hitpoints of damage (equivalent to 100-200 LP after an update on 3 March 2010, and roughly 1000-2000 LP in the Evolution of Combat). This glitch was later fixed.
 * The knife's inventory graphic was changed unannounced with the Elemental Workshop III update of 25 May 2010. The update made it look much sharper.
 * Seven knives are one of the ingredients of Iron Beer.
