Seeking to create a pen that was lightweight and comfortable, and would reduce the cramping that is usually associated with long periods of writing, Boyd finally arrived at the design for the Sensa pen after numerous prototypes and designs.
Setting out to design the world’s most comfortable pen, Boyd consulted with ergonomic specialists and researchers to perfect the weight and balance of the pen. The finished product – the Sensa pen we know today – implemented a plasmium fluid gel grip that molds to the users finger to reduced cramping and maximize comfortable grip. The wear and pain that normally occurs during extended note-taking or composition is reduced by up to 50% using this patented design.
While many ball point pens often become the object of absentminded tapping and twiddling, this is not a good idea with a finely crafted Sensa pen. The ink chamber is pressurized using nitrogen gas, and tapping the tip on a hard surface can release the gas prematurely and spoil the pressurization. Similarly, caution should be used when dismantling the pen, as the spring that holds the ink cartridge in place can easily be lost. Replacement ink cartridges do not come with replacement springs, so loss could theoretically necessitate replacement of the pen itself.
The Sensa pen has now been discontinued, but will always be known as the World’s Most Comfortable Pen. This customized writing device that took a decade to craft continues to be collected and marketed by enthusiasts around the world. Like so many other discontinued classics, the Sensa pen has achieved a kind of cult following of pen enthusiasts who swear never to use another pen.
