The Redstone Tool Enhancer

Instead of a new tool tier, I think that there should be an item that is charged with Redstone and would be equipped on tools to make them go faster, but still use the same durability per block, and for weapons it would make the weapon deal as much damage as to kill the mob that is being attacked, but is capped at a certain amount of damage (you aren't going to be able to one hit the Ender Dragon or the Wither), but also use the same durability as if the weapon was used as many times as it would take to deal the same amount of damage normally. To equip it on tools, you would put the item and the tool in the crafting grid, and to charge it you would put the Redstone and the item or the item on a tool in the crafting grid, and to unequip the item you would just put the tool on the crafting grid and the item will appear in the slot on the right and the tool will appear in the crafting grid.
