String (Also known as Silk) is an item that was introduced to the game by Indev, the older test version of Survival Mode. It can be received by killing a Spider, which will drop up to two units of it. String is a necessity to make a Bow and Fishing Rod, and can be used to make Wool as well, despite being much harder to get than wool from Sheep. String can also be collected by shearing Cobweb off the walls of an Abandoned Mine Shaft with Shears or a Sword. This can can be a excellent source of string as abandoned mineshafts are abundant with cobwebs. Another, but slightly more difficult, location to find string is in Dungeons. As of the Minecraft 1.3.1 Update, String can now be placed on the ground as Tripwires, and can be combined with Tripwire Hooks to create a Redstone trap.
