Supertools would be like regular tools, only significantly better. they'd require a similar material, but it would be harder to make them.
For instance, super pickaxes would be crafted like so:
<--- pretend those are iron blocks
<--- pretend those are gold blocks
in the case of armor, I dunno what super leather armor would be made with (saddles? XD)
I feel that the diamond and gold supertools could be a neat idea, like the gold one being incredibly fast and the diamond one having an insane amount of durability, but I don't see much reason for the iron or wood ones. Would they have some sort of neat trick? Because just being a little faster, or more durable, would put them about the same level as one or two elvels past what they are, which already have tools at that level. Like if the wood one was more durable, it might last about as long as an iron one, but it wuld be slower so less desirable. Something along those lines.
