Custom materials for tools?

[blocks119]

Hi, I know you can make custom materials for armor and there is a decently long list of ones for blocks howerver is there any way to create custom materials for tools , for example for bronze tools that can mine gold but not diamond?

im fairly new to this so if its obvious please have some patience with me

thanks :)

I'd also be intrested to know if there are any other worldGen types besides worldGen:ore because id love to make some plants that generate on the surface of the world

much thanks
