Parker employed this special technique in most of its top-selling pens until 1928 (The only alteration to this system occurred in 1898 when the under-feed system design replaced the Lucky Curve).

In 1894 Parker pen created a pioneering anti-leak ink system called the Lucky Curve. It featured a curved hockey stick shaped ink system that channels excess ink back to the ink reservoir through capillary action, reducing ink leakage. It was breaking news at that time as it was the first time a fountain pen could be carried in pockets. This became a standard in Parker pen designs for the next 30 years. To further save guard the users from the embarrassment of an ink disaster, the Parker Pen Company created and patented the slip-on outer pen cap in 1898. Now its even safer for one to stuff his Parker fountain pen into his pockets.

The product was thought of as perfection because the vital parts of this fountain pen were encased inside the barrel ensuring no leakage at any time.

In mid 1934 Parker began marking most pens and pencils with a date code, both the barrel and the nibs were marked, but lacking a date code doesn't necessarily mean that the pen was made pre-1935, since many imprints have been worn off with use. The first date codes, found for example on the Vacumatics, consists of two digits, the first one denoting the quarter of production, the second denoting the production year. Hence a "47" marking on a 1930's pen indicate that the pen was produced in the fourth quarter of 1937, not 1947, which is a common misconception.

Parker saw the pen she rejected it because it looked too much like blood, although later Parker used essentially the same color in its Parker 61 line. The below illustrated pen is unique in that in addition to its red color, it has an original factory single gold filled barrel band, similar to that illustrated in the early patent artwork.

Parker employed publicity stunts, such as throwing these new pens over the Grand Canyon and out of an aeroplane at 3,000 feet, to prove their durability.
