I am a man in a suit who has fallen into the world of Minecraft.
Six stone bricks make four stairs at a crafting table or six at a stonecutter. For slabs, the same six blocks make twelve either way. The stonecutter saves material on stairs and lets you make smaller batches of slabs and walls. This guide uses the Minecraft Java Edition 1.21.11 recipes.
How to craft a stonecutter
On a crafting table, place three stone blocks in one row, then put an iron ingot directly above the middle block. The recipe needs regular stone, not cobblestone or smooth stone. If you only have cobblestone, smelt it in a furnace to get stone.
How to use a stonecutter

Put the material in the left slot, choose a recipe in the middle, then take the result from the right slot. This screenshot is from Episode 119, when I dug the grand canal and cut the stone into stone bricks.
Regular stone can go straight into stone brick stairs, slabs, or walls without making stone bricks first. Stone stairs and stone brick stairs are different items, so check the output name before taking it.
What six stone bricks make: stairs, slabs, and walls
- Stone brick stairs: four at a crafting table, six at a stonecutter.
- Stone brick slabs: twelve either way.
- Stone brick walls: six either way.
For 24 stairs, you need 36 stone bricks at a crafting table or 24 at a stonecutter. Slabs and walls use the same amount of material either way, but the stonecutter lets you start with one stone brick and make just two slabs or one wall.

In Episode 120, I built a hot spring in the castle town and used stonecut stairs and walls on the way up from the bathhouse. When you need just one more stair, it is handy to cut it from a single block.
That is all for this time.
