Actually, there are a number of knife makers that use salt pots, Kevin Cashen comes to mind and I think Ed Caffrey may also have worked with pots. There are some things you can do with salt pots that simply cannot be done any other way.
Nevertheless, Jim is right that most of us don't need salt pots. They are dangerous and they are expensive to maintain. Unless you understand metallurgy like Cashen does there's no point in messing with pots ...
