Sword

Swords are weapons that kill mobs or players (if multiplayer PvP is on) more quickly than with bare hands. They also remove all blocks faster than using bare hands (such as leaves, wool, and Soul Sand, though especially Cobwebs), but each broken block counts as two uses on the sword's Durability Bar when it is used in this way. Stone (or better) swords revert minecarts in one hit with no decrease in durability, whereas wooden swords require two hits. Killing larger slimes with a sword will also prevent more slimes from spawning. In The Nether you can find Zombie Pigmen that use Golden Swords, but they do not drop their swords when killed.

Uses

A sword is used to attack mobs and other players or to block attacks (since 1.8). It can also be used to destroy some blocks faster than by hand, but will damage the sword more.

Materials that swords destroy the fastest

Crafting

Swords are created with 1 stick and 2 units of a tool material:

Ingredients	Input » Output	Description
Sticks + Wooden planks or Cobblestone or Iron Ingots or Gold Ingots or Diamond Gems	Template:Grid/Crafting Table	Deals more damage to mobs than by hand.

The following table summarizes the damage that different quality swords inflict.

Material	Bare hands	Wood	Stone	Iron	Gold	Diamond
Durability	∞	60	132	251	33	1562
Damage
Critical Hits
Approx. Number of Kills	∞	12-20	33-66	83-125	6-11	781
Lifetime Damage Inflicted	∞	120-240	396-660	1004-1757	66-132	7810-12496

The formula to find the total lifetime damage is Durability x Damage per hit = Lifetime damage.

Combat

The sword is a short range weapon - despite its appearance, it grants no range advantage over any other tool as of Beta 1.7, including bare hands. Swords used to inflict more damage than bows - often significantly more depending on material, and even a wooden sword was on par with an arrow, but since the beta 1.8 update the only sword that can match a full powered arrow (with a standard hit)is the diamond sword. A way to use swords without being hit (and thus closing the gap between swords and bows) is to dig a trench such that the player's head is the same level as the mob's feet.The player must of course have blocks over his head so that mobs do not come into the trench. It is then possible to hit mobs without them seeing the player: this prevents mobs from retaliating. This method is efficient when defending a fortified building, but is nearly useless when exploring except against the 2-block wide Spider.

High damage swords are primarily advantageous because they kill mobs in fewer hits, defeating them faster and thereby reducing the chance of being damaged in return. For the same reason, you will swing these swords fewer times in the long run, reducing the rate at which Durability is expended. Unless the player engages in combat very frequently, swords in general will see a far longer useful life than say, a pick or a shovel which may be expended in a few minutes of intensive excavation. This causes diamond swords in particular to last an extremely long time. Some players may find that this weapon can easily outlast them, being lost due to accidental death in lava or otherwise rendered beyond post-mortem retrieval long before it is actually used up. A diamond sword's 5 over the iron sword's 4 is also a much bigger difference than the difference between the numbers may imply as it guarantees a kill of any aggressive mob (or an unarmoured player) in two hits, and any passive mob in one. The ability to kill rapidly is of greatest benefit against creepers and ghasts when the time to act may be very short. These factors combined make a diamond sword a compelling investment.

As of Beta 1.5, but before Beta 1.8, all melee attacks, including hands, do half a heart more damage, making the stone sword arguably nearly as effective as the iron one as it kills most mobs in the same number of hits. If the player combines swordplay with archery, the iron sword's extra damage will save a some arrows and closely matches performance with the diamond sword.

The weaker swords are not recommended for creeper combat (especially on normal or hard) and there are strong arguments for using a bow, owing to its range (provided the bow is at full charge). If you approach a creeper with a sword, a recommended strategy is to use hit-and-run tactics. Hit the creeper and run away until the hissing stops, then run forward and hit it again, as many times as necessary. With a diamond sword, however, one may simply charge at the creeper whilst swinging it, as the 2-hit-kill allows the player to kill the creeper prior to their "fuse" running out. Be wary, as this is a dangerous tactic that requires a bit of practice, and the creeper may move out of the way, often ultimately leading to the demise of the player. Creepers tend to spiral in on their targets in a counterclockwise fashion, so one might find it helpful to remember to move one's cursor to the left as the creeper strafes.

With the ability to sprint added in Beta 1.8, swords became a more effective tool in combat: when a mob is hit by the player when sprinting, they are sent flying several blocks back. This is quite useful when fighting creepers. Charge at them in a sprint and hit them, they get knocked back to a safe distance before they could even initiate their self-destruct countdown, just repeat until the creeper dies. Just make sure there is room behind the creeper and that it does not get knocked back into an obstacle for maximum effect. This tactic basically eliminates the need to run backwards before going for another hit. This tactic is not recommended for tight areas such as caverns and other tight spaces, only do this when you encounter a creeper in the open. Players are advised to make use of the critical hit ability of the sword to dispatch of mobs, especially creepers, quickly. A difficult, but effective manoeuver is a combination of both knock-back and critical hits, sprinting towards the enemy before jumping and landing a blow on them before landing. This will both deal heavy damage and knock the mob far back, fall damage often finishing the mob off. Sprinting is also good for closing the distance on skeletons and ghasts, but make sure to not hit them while you are sprinting or they will get knocked back, allowing them a free shot at range.

As of Beta 1.8, swords are able to block attacks by holding the right click button. This will block arrows as well as other projectiles, but will reduce the player to a speed slower than sneaking. Also, when sprinting at an enemy and then right-clicking when within hitting distance you will send the enemy farther than sprint-attacking them but will deal no damage. Swords and all other player-dealt damage were also reduced by half a heart in the 1.8 update (like before Beta 1.5).

Bugs

In 1.8 Pre-release while holding sword if you double-click the use -button (Right mouse button as default) you will sprint. This is fixed in the official version.
In 1.9 Pre-release 4, blocking with an enchanted sword will cause the sword to visually flicker for the wielder between blocking and not blocking.
Using the /give command, swords can be stackable. This also includes other tools (Such as Pickaxes)
