My bad Greg,
I meant shapeless as in when you place an ingot in a grid, you can either receive nuggets or chunks depending on where you place it. I don’t know the term for this, grid-specific perhaps? You can place the bone+flint combo anywhere on the grid and it will produce a flint knife.
I think the idea in witchery is that you shave or chip the bone with the flint to produce a needle. I believe their recipe calls for the Bone in the left corner and Flint in the middle top:
