The Stonecutter can create oxidized doors and trapdoors directly from oxidized copper blocks
The Stonecutter can be used to create all wood produces at the same price, or a very small discount (in this case, 1 log = 4 planks = 4 stairs, crafting table would use 6 planks).
Bricks can be converted back to the base block (here, Stone). Stairs can be converted back to blocks, etc.
Like Stones, wood objects can be returned to planks, or sticks, if they would yield too much as planks.
Slabs can be converted back to blocks (crafting table).
Deepslate can be converted to Cobbled Deepslate, and from then, to all the Deepslate variants.

OmniCut is a quality of life datapack: the Stonecutter cuts wood logs to wood items, cut oxidized copper doors, convert stone blocks back and forth, and recycle wood items. Prices are set in the spirit of the vanilla game with minor discounts, if any.
