Seperate tool types for grimstone

Right now, grimstone/deepslate can be crafted into stone tools and the same furnace that cobblestone and blackstone can. I think this should change, because risk should equal reward. The grimstone layers are riskier to be in, so I think you should increase the reward by having a new tool type called grimstone/deepslate which mines faster and has more durability than stone, but not as much as iron. You could also have a grimstone furnace which either uses less fuel or takes less time to smelt items. This is different than blackstone because, blackstone is in a different dimension where you cant get cobblestone, so you need an immediate replacement, and the farther down you go, the reward you get should be better. Anyway, there is already stone in the overworld, so I think grimstone should have its own toolset. I am a huge fan of Minecraft and I appreciate all the time and effort the devs put into working on the game! thank you!
