The attention production efficiency and the intent to pursue a policy of industrial expansion always remain a constant in the history of [[Wahl Eversharp]], as well as the presence of wrong investment decisions, such the one that caused the decline and the end of the company. The first of these misplaced investments was, in [[1922]], the acquisition of a factory for the production of hard rubber tubes. This led to some of the most beautiful pens in hard rubber ever produced, but the investment was wrong, as it was done just before the advent of celluloid pens.

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 [[Wahl Signature|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 ''[[Ink Shut-off]]'', illustrated in the figure, was just another wrong investment: promoted as a mechanism capable to block the flow of the ink form the pen when the pen was closed, to prevent leaks because of pressure changes, (as was the case when travelling by plane, activity that was booming) it was indeed ineffective, so that the company was forced to withdraw it from the market by an order from the Federal Trade Commission.
