The knapping interface is a 5x5 grid. Clicking on a square of the grid will break off that piece of stone. Be careful where you click - if you make a mistake, you cannot undo it and you will have to start again. If you successfully create a specific shape, a tool head will appear to the right which can then be attached to a stick or a bone in the crafting grid to create a stone tool. While knapping, Stone Flakes might be produced, which can be used to craft arrows later on.
