Many German, Swiss and Dutch small cigars (e.g. Schimmelpenninck) are dry-cured. They are intended to not be stored in a humidor, and in fact are difficult to draw if stored at 65% RH or higher.
"Kentucky" Cheroots usually include a bit of dark fire-cured leaf. Otherwise, dry-cured cigars can be of any tobacco. Many German and Dutch dry-cured cigars use a Sumatra wrapper, though I've had pure Brazillian cigars, made by Villager (Switzerland), that were dry-cured. The fatter the dry-cured cigar, the more easily it will draw if humidified.
As for making them, keep in mind that the wrapper and binder dry more rapidly than the filler, and the filler dries quickest at the open foot (and open head, if present). If any cigar is allowed to dry out too rapidly (say on your dashboard), the wrapper and binder tend to split, especially at the open end(s). So the key is to allow them to dry slowly. Once fully dried, keep them sealed in a bag, so that fluctuating humidity won't cause a later crack.
