Dragon pickaxe

The dragon pickaxe is a pickaxe. Made out of dragon. Which isn't actually a metal, unsurprisingly. Apparently, Jagex couldn't be bothered to research real metals so they made up their own...

But I digress, the dragon pickaxe is - to the best of my limited Powerscape knowledge - the best pickaxe you can get. It's the best in terms of stats, i.e. it mines faster and looks cooler. It is also the only pickaxe that wasn't modelled by an ape.

If you look at the Wikia Page logo, you will see a rather handsome player wielding a dragon pickaxe (or 'pick', because apparently it's too hard to type pickaxe) and therefore there is no need for me to put up an image.
