Kaweco Titan Sport Titanium Fountain Pen

A titanium version of Kaweco's Sport, the octagonal pocket pen the company has made since 1935. Closed, it's short enough to disappear into a pocket; posted, the cap brings it up to full writing length. The body is machined from solid titanium in a glossy deep grey finish — light for its strength, and, unlike the brass and bronze Sports, resistant to the patina bare metal usually takes on.

What makes it special

• Solid titanium body and grip section — strong, and light for a metal pen at about 26 g
• Doesn't patina: where Kaweco's brass and bronze Sports darken with age, titanium won't oxidize, so the grey finish stays as it started (as uncoated metal, though, it will still collect the small marks and scratches of regular carry)
• Sport proportions — about 10.5 cm closed, 12.7 cm posted: small in the pocket, full length in the hand once posted
• German-made stainless steel nib by Bock, iridium-tipped, and interchangeable with Kaweco's other Sport nib units
• Comes ready to write with a Royal Blue cartridge, in a silver Kaweco tin with a black sleeve
