Kaweco Ballpoint Pen Sport AL Raw

The Kaweco Sport AL Raw is a pocket ballpoint made from raw, untreated aluminium – compact, solid and with a surface that develops character from the outset. The aluminium is left raw: the traces created during CNC machining form a characteristic, slightly rough texture that feels cool and grippy in the hand and develops its own unique patina over time. The heart of the pen is the heart cam mechanism, which extends and retracts the refill silently – no clicking, no vibration, just a gentle, precise stroke.

Features

• Raw aluminium: The surface is neither painted nor anodised. Scratches and wear marks become part of the character – each pen develops its own distinctive appearance over time.
• Heart cam mechanism: The refill is extended and retracted silently and precisely by pressing the button. No annoying clicking, even in quiet environments.
• Octagonal aluminium body: The eight-sided profile sits securely between your fingers and won't roll off the desk. The weight of the metal gives this compact pen a satisfying heft in the hand.
• Compact format: At 10.5 cm long, the Sport AL Raw is a true pocket companion – it fits into any trouser pocket, any notebook spine, any keychain clip.
• D1 refill in standard format: The included blue ballpoint refill can be swapped for any Kaweco D1 refill – available in blue and black, in line widths of 0.8 mm, 1.0 mm and 1.2 mm.

Use & Tips

• Daily companion: The Sport AL Raw is ideal for quick notes on the go, signatures, to-do lists – anywhere a ballpoint needs to be within reach without drawing attention.
• Choose your refill to suit: For smooth, saturated lines on smooth paper, a 1.0 mm or 1.2 mm refill is recommended. For more precise writing – such as in tight grids or small calendars – go for the 0.8 mm version.
• Actively develop the patina: If you want the raw finish to age deliberately, carry the pen without additional protection in your trouser pocket. Contact with keys, coins or rough fabric will mark the surface and enhance the industrial character.
• Clip optional: The Sport AL Raw is supplied without a clip. A Kaweco Sport clip can be added separately and attached to the top ring – ideal for those who want to carry the pen on their shirt or notebook cover.
• Pair with the AL Sport fountain pen: The ballpoint looks and feels great alongside the Kaweco AL Sport fountain pen in Raw – both made from the same untreated aluminium, both in the same compact format.

For Writing Instrument Enthusiasts

The heart cam mechanism is a special pressure mechanism where a heart-shaped cam guide ensures that the refill alternately extends and retracts with each press. Compared to simple pressure mechanisms, it operates without springy clicking and without perceptible play, which is particularly noticeable in the hand: the stroke feels damped and controlled. The D1 refill is the short format used in Kaweco Sport and Liliput pens and can be replaced with many compatible alternatives – including oil-based ballpoint refills for particularly fast-drying, smudge-proof writing. The untreated aluminium of the Raw model is not sealed and responds to moisture and oxidation; to prevent this, you can occasionally wipe the surface with a dry cloth or treat it with a touch of metal care oil.
