this mod ads 2 new toolsets that can mine in multiple modes such as 1x1, 3x3.
craft armor with potion effects and make a paxel that can mine any block you can mine with a pickaxe, an axe, a shovel or a hoe.
ctrl right click to change the mode of the tools so you can use it as an normal tool for the precise work

you do no longer need 5 tools in your inevntory but you can have single tool that does al the work.

a Hoe has a 9x9, 3x3, 1x1 mode
the other tools have a 1x1, 3x3 mode
and the paxel can mine all blocks that the normal tools can mine and has a 1x1 and a 3x3 mode

i hope you like the mod i have put a lot of effort in creating it.
thanks for your time
