Copperplate is a general term for a family of styles which grew out of classic italic in the 17th and 18th centuries. Spencerian, a similar lettering style, developed in North America and by 1860 was taught as standard handwriting in schools. Copperplate and Spencerian are among the most elegant of hands. They are different from other calligraphy styles as they use pressure to produce lines of varying width.The use of an oblique nib, or straight nibs in an oblique penholder, enable the writer to keep the nib pointed in the direction of the slant while maintaining a comfortable writing position. Use of the oblique penholder means a variety of nibs can be used.
