Heading to the mailbox after days away? We usually overlook the bills and go straight to the letters and cards sent to us from friends. Letter openers help us to open well-travelled correspondence with little more than a flick of the wrist. Better still, letter openers help to preserve the envelope and exotic stamps in which the letter may have been sent. There's quite a selection, especially at tag sales, a great opportunity to search for one that fits your personality.
