In [[1948]] it was made what is perhaps the most significant invention in the Italian fountain pen production, the [[Omas 361|361]] model. Born as a response for the success of [[Parker 51]], the originality of the pen is in the central position of the nib, mounted on the axis of the pen, around which is placed an hood open by one side. Depending on the position of use of the pen, and in particular of the open side, the nib can be almost completely covered, resulting in a rigid nib, or left uncovered, allowing a flexible writing. A grading system suddenly very functional, so that it is told that the [[Parker]] tried several times to acquire the patent ({{Cite patent|US|2565667}}) from [[OMAS]].
