  In [D.A. Fedoseev, V.O. Manturov, A sliceness criterion for odd free
knots,arXiv:1707.04923], the authors proved a sliceness criterion for odd free
knots: free knots with odd chords. In the present paper we give a similar
criterion for stably odd free knots. Some additional results on knot sliceness
and cobordism are given.
