We got through about three nails eventually but leaving them seemingly sharper than they were before. Then on the fourth attempt the clippers literally sprung apart sending bits flying.
So here's Suse trying to use one of her emery boards to smooth the edges. By the way, it didn't work. I think next time will take him to Beresford at Lewisham where some of Charlie's friends get their nails clipped! But it was fun trying.
