Its weird that we can split hides into multiple pieces and recipes that call for hide will count individual inventory squares, meanwhile we have moose antlers, mammoth tusk, whale bone etc that is massive and still only counts as a single piece of bone in "bone material" recipes.
We should be able to split larger bones into separate bone materials and not get stung on recipes asking for bone material treating a 6 slot bone as the same the bone from a squirrel.
