A double is both, as Mac stated. A plain Double by a quality maker will be the best tool that you can use for it's intended purpose. It will shoot to point of aim, function flawlessly, balance perfectly, fit purposefully and respond like the your old 17 year old girl friend.

If a rifle is beautifully done, intricately engraved, with gold accents, special innovations and beautiful wood it will do everything just as well as it's plain cousin. It will look much prettier but will also function as well.

All Doubles are made to, first be useful tools and second to be aesthetically pleasing.
