Selective Grindstone

Selective Grindstone is a minecraft mod to allow using an enchanted book to select which enchantments should be removed from an item placed in a grindstone. If you input, for example, a diamond sword with Sharpness V, Unbreaking III, and Looting II and a sharpness book (of any level), only the sharpness enchantment will be removed. This process does not consume the enchanted book that is input.

The mod also has a config allowing curses to be excluded. This config also includes the ability to make the default grindstone accept curses as well (though this is set to false by default).

There is also an alternative grindstone recipe included to make it take one stone block rather than a stone slab (since it's so wasteful to make multiple slabs and only use one).

The mod requires YACL due to the above config.

The mod works purely server-sided, though it has mod menu support for configuring it for singleplayer.
