Currently, all of your Stair recipes output 8. In Vanilla, all stair recipes output 4, while the Stonecutter recipes give a 1:1 ratio. With the current Create recipes, Stonecutter stair recipes give worse return than just crafting.

Good point. I suppose I was too used to having stair recipes output 8 in 1.12.

Or 1:1 using the stone cutter
