The Exoskeleton is based on a Voronoi pattern, a cell structure that shows up all over nature, "from microscopic cells in onion skins, to the shell of jackfruits and the coat of giraffes." Cutting it through a Bolt Action body takes 28 minutes per pen in titanium, and the main program plus its seven subprograms add up to 126KB, almost double the 64KB our machine can store. It's offered three ways: polished and anodized Titanium, polished and flamed Titanium Damascus, and Aluminum in black DFL, a dry film lubricant Cerakote with an incredible feel.
