Armature ‣ Subdivide

You can subdivide bones, to get two or more bones where there was just one bone. The tool will subdivide all selected bones, preserving the existing relationships: the bones created from a subdivision always form a connected chain of bones.

Number of Cuts

Specifies the number of cuts. As in mesh editing, if you set n cuts, you will get n + 1 bones for each selected bone.
