70 Dollar Saturday – Tumbled Copper Mk II Bolt

70 Dollar Saturday

The new Mk II profile was initially a design element added to our prototype release of the Retraktable mechanical pencil. Initial feedback from early users moved this new grip profile from a prototype to a standard option on the Retraktable, but also a special release option for the Bolt and EDK. Why Mk II? Mk II (later Mk 2) was the nomenclature of the fragmentation anti-personnel type hand grenade used by the United States from 1918 through the 1960s. Often referred to as the “pineapple grenade” due to its strange outward appearance, it was also called the “frag”. Our Mk II has a similar “frag” pattern milled into the grip area that provides a nice tactile feel and looks cool too.
