Advanced Mining Speed when Dual Weilding

So a great, realistic idea to be added could be how when Dual Wielding pickaxes, sticks, pickaxe and stick etc, it should boost mining speed and efficiency. For example, if the character holds a pickaxe in their main hand and a stick in their offhand, their mining and attacking efficiency and speed will increase.

This may not have made sense, however I hope you were able to receive a basic idea from it.
