Some nibs were designed with tips that angle upwards. Virtually all of these were made by Sheaffer, starting in the '30s. Sheaffer's conical Triumph nibs, introduced in 1942, all display this feature. Some Parker Duofold nibs were made with a turn-up, but they are rather rare. Turn-up nibs place the iridium tip more nearly parallel to the writing surface, and so are especially suitable for left-handers and others who hold their pens at a steep angle.
