Replicating the Diamond sword from Minecraft (data value 276 to be precise), the Minecraft Deluxe Diamond Sword is an officially-licensed Minecraft product.
It is made from sturdy EVA foam with blow-molded plastic details, which means the Minecraft Diamond Sword will withstand far more than 1562 uses.
EVA makes the Minecraft Diamond Sword a sturdy tool, hefty yet with enough cushion that you'll feel comfortable using to slaughter a wide variety of baddies.
And, of course, this is an officially-licensed Minecraft product, which means you're making Notch happy, too
