My wife and I are taking a trip to London in the Summer for a full week. I can probably manage a half day to visit a couple antique shops/malls in the city during our vacation.

I am primarily on the look out for straights and natural hones, but strops and brush handles are also on shopping list. I also like to clean up vintage pieces, so no new retail shops please.

Any suggestions on which antique malls or shops I should not miss on my trip? Thanks for the help!
