Conical Nib
Companies began making cone-shaped nibs in the 1940s. The most famous conical nib is likely the Sheaffer Triumph nib. Unlike an “open nib,” which leaves its inkfeed totally exposed, a conical nib wraps around the inkfeed to minimize ink evaporation. Stylistically, they are quite attractive, but we don’t know if they minimized much ink evaporation. In our experience, these tend to be very firm nibs with a lot of feedback.
