--[[ TOOLS SUMMARY:

Tool types:

* Hand: basic tool/weapon (special capabilities in creative mode)
* Pickaxe: dig cracky
* Axe: dig choppy
* Shovel: dig crumbly
* Shears: dig snappy
* Sword: deal damage
* Dagger: deal damage, but faster

Tool materials:

* Wood: dig nodes of rating 3
* Stone: dig nodes of rating 3 or 2
* Steel: dig nodes of rating 3, 2 or 1
* Mese: dig "everything" instantly
* n-Uses: can be used n times before breaking
