Knife bug

The so-called knife bug was a bug that allowed players to equip multple knives (not intended to be wieldable) and have a high attack and strength bonus.

To punish players, Jagex set up a script that did the following:


 * Players with knives equipped while in the Wilderness died instantly upon logging on (much akin to divine punishment)
 * Players with knives equipped while outside the Wilderness simply had them disappear
 * Players with knives merely in their inventory were not affected at all

When Jagex took manual action, players who PKed with the knives were permanently banned for bug abuse, while players who trained with them were temporarily banned.
