Last two: 15ac Makes smart new cut when running out of 10 (7). n???e?s I have neatens but can't quite see it, the answer to 10 if that is relevant is axiom.
6dn They're tossed about on holiday, maybe stranded if separated? (5,5) I have b?a?h/???l? I thought beach balls but can't work out the maybe stranded bit.
