Minecraft* You need a stone pickaxe to mine iron in Minecraft.
No you don't need the Axe to get iron in minecraft.However you do need a stone pickaxe to be able to mine iron ore.Otherwise you wont get the ore and the iron ore block will just disappear when you eventually break it without a stone pickaxe or better.
If you dont have a diamond/gold pickaxe you may still get diamond/gold by using iron pickaxe
From new, a diamond pickaxe will break after 1562 uses, making it 6.2 times as durable as an iron pickaxe. Note that breaking a block that a pickaxe is not optimal for breaking counts as two uses. Source: Minecraft Wiki
