Throughout the first part of '20s the company continued to produce pens in hard rubber, the line [[Tempoint]] was completed in [[1922]], the pens in hard rubber produced since [[1923]] are called frequently by collectors [[Signature]] using the nib name. But despite being produced in many different versions both in style and materials, the company continued to refer to them simply as ''Wahl Pen''. The pens were produced in different sizes depending on the nib, the wheel clip was reserved for models of biggest dimension, for nib measures 4 and 6, while to meet the [[military clip|military regulation]] was introduced a model with a elegant curved clip, welded directly onto the metallic head of the cap, with an elegant tulip shape, which is indicated by collectors as ''[[Tulip Clip]]'', that was produced in two sizes. The pens were made in black or red hard rubber decorated with engravings, which in [[1926]] was added the ''Rosewood'' color.

Due to the heavy investment made [[Wahl Eversharp]] was late on the field of materials and began production of celluloid colored pens in [[1927]], lagging behind competitors (between the [[Big Four]] only [[Waterman]] was slower to adopt the new material). Initially were introduced only three colors: ''Jade Green'',''Royal Blue'' and ''Coral'' while maintaining the production of hard rubber pens.

The next year the company completely redesigned its line of products, going almost totally to celluloid, also for the Black and the ''Rosewood'' colors, and introducing the new ''Black Pearl'' color; but some of the new models still made in hard rubber can be found. The big novelty however was a revolutionary mechanism that permit to use different kinf of nibs on the same pen, called ''[[Personal Point]]''. Up to 14 different nib types were available, which, thanks to a screw mechanism, could be mounted directly on the pen by the dealer.
