My wife recently bought me a new Zavvos pipe which, according to the eBay listing, was made between 1979 and 1982. It's a new pipe; never been used. I was wondering, would the briar on that pipe have benefited much from the past 30 years or so? I know it's good to age briar blocks before they're made into a pipe, but what about after the pipe is made? Does the briar on a finished pipe still improve with age? Thanks.
