Engineer’s tools adds a few useful perks to Minecraft. The REDIA tool combines pickaxe, axe, shovel, and shears into one multitool. You can use it to shear sheep and grass and leaves:

You can then start a farm without changing tools. Tilling soil or creating paths by sneaking while right-clicking is a breeze.

And if you need to take out a tree quickly just sneak while chopping and the whole thing comes crashing down.

Then head down to your mine and the same tool will place your torches for you without needing to switch to them or even have them in your hotbar.

Now that you have light this mod gives you another useful tool with Ariadne Coal that places arrows to help you keep track of where you’ve been. The arrow will place in the direction you are facing and it can be placed on floors and ceilings as well.

And then the tool functions like any other pickaxe for all your mining needs.
