This simple mod will add variety to the creation of pickaxes, and add new material to fix them. I will continue to develop this mod further and add new pickaxes! The mod was created using MCreator

At the moment there are three levels of picks that surpass each other by 10 efficiency:

Level 1 - 20 efficiency
Level 2 - 30 efficiency
Level 3 - 40 efficiency
Level 4 - 50 efficiency
Level 5 (max.) - 50 efficiency and mining radius 3x3x1(the most painful pickaxe for me, I decided not to use ready-made procedures, and write my own from scratch, so if you have any problems, let me know in the comments. At the moment, 3x3 mining works by checking the light side of the player's gaze and due to this it is decided which specific blocks to break, it is confusing, but as for me it is better than the blanks I found for 300 lines, mine takes only 80)

Warning

In minecraft 1.12.2, there is a problem with "ghost-blocks" when the efficiency of the tool is too high, if you encounter this problem when using 3-5 levels of picks, install THIS mod!
