Well, from a purely technical point of view, there's nothing innately superior to making a pipe by hand than machining it. BTW, artisans use plenty of machinery in making their pipes. The difference is that a purely machine made production line will generate less "firsts" as the cut down stage has been eliminated. It's that cut down stage, where hand shaping is employed to remove natural defects that crop up in the bowl shaping, that provide a higher number of "firsts".Getting back to Dunhill how can machine manufacture do as good a job as an artisan could do?
Dunhill has never been purely a pipe making concern. Their focus was always on supplying quality goods to the high end market. What Dunhill did that was brilliant was to promote the IDEA of Dunhill as the symbol of success, the good life, the very finest quality that could be obtained. To own Dunhill was to show the world that you had arrived and that you were discerning and had taste. And, they did this not just with pipes but with all of their various goods, leather, silver, gold, etc. Dunhill isn't a pipe, it's a status symbol
Ask a non smoking person to name a pipe brand and they're far more likely to know the name, Dunhill, than any other.
Are they a good value for the buck? That's for you to decide. I own a bunch, and I rarely smoke them anymore. I've found other pipes that perform much better for me that most of my Dunhills. I do have a couple that stay in the rotation. I wouldn't part with them.
As for their history, it's a rich history, though not without some telling controversy, and it's certainly not the longest, oldest, or most fabled. You can look to Charatan, Loewe, Barling, Comoy, BBB, amongst others, for that. Dunhill is just the best known and most promoted.
The three tier one Dunhill dealers with whom I've discussed the brand and their history all say the same thing. At their best, a Dunhill is as good as any pipe made by anybody. But their output over the years is uneven, and their focus has always been on making the finest stems with excellent fit and finish, rather than providing the best briar. And that's because most smokers don't know briar, but they do know stems. Two of the three said, mediocre briar, world class stems.
For those who love status symbols, Dunhill will always be The One.
