AutoSwitch Mod 1.6.4

AutoSwitch is a highly-configurable, advanced mod that automatically switches to the correct tool when mining a block and automatically uses the correct weapon when attacking a mob or a player. It will also switch back to your previous item when you are done mining or attacking a mob, useful for building and going on mining trips.

AutoSwitch will look at every tool in  your hotbar and pick the best one to use, using a complex algorithm that doesn’t just use the fastest tool, it also takes into account other factors such as enchantments like Silk Touch or Fortune, and if the item is damageable or not.
