The Knife bug was an event that happened in 2003 in RuneScape Classic. There was a bug that allowed users to equip an amount of knives, and therefore giving them a high Strength and Attack bonus. BuffySlayer reported a loss of a runekite shield, a very vauable item at the time, when she was killed after logging on with a knife equipped.
JaGeX temporarily banned all players who trained with these knives and permanently blocked all users who PKed with the knife.
JaGeX also created this script as a punishment to the bug abusers.
- Players with knives equipped while in the Wilderness died instantly upon logging on.
- Players with knives equipped while outside the Wilderness simply had them disappear.
- Players with knives merely in their inventory were not affected at all.
