Matthew, the son of famed knife-maker RJ Martin, built this pen from carbon fiber and Grade 23 Extra Low Interstitial (ELI) titanium, an alloy used in surgical implants due to its toughness. The pen includes a sharp striking tip and comes with optional rubber O-rings, which fit into grooves on the body for added grip. It accepts a Fisher Space Pen or Parker-style cartridge with the included titanium spacer inside the body; remove the spacer, and the pen can accept a larger Pilot G2 gel cartridge.
