Pressing the rear button opens the clutch so the 5.6 mm lead can be extended, shortened, or replaced. Unlike a conventional mechanical pencil, the mechanism does not advance the lead by a fixed increment; the user sets the exposed length directly. The removable push button also contains a lead sharpener, making it possible to move between a fine point and a broad edge while working.

The included 5B graphite lead is soft enough for dark lines, loose sketches, and broad shading. It can be used from the point for narrower marks or along its side to cover larger areas. Replacement Kaweco 5.6 mm graphite leads are sold in packs of three.

At 44.2 grams, Sketch Up is deliberately heavy for its compact size. The untreated brass begins with a brighter surface and gradually develops fingerprints, darker areas, scratches, and polished sections through handling. This changing patina is an expected property of the material.

The clutch also accepts compatible 5.6 mm colored leads, highlighter leads, and Kaweco eraser cords. Clean the mechanism thoroughly when changing between graphite and eraser inserts to prevent graphite residue from transferring onto the eraser.

The design returns to an earlier chapter of the Sport’s history. Kaweco introduced a piston-filled Sport under the model number 612 in 1937. The current aluminum version, released in 2024, retains the pocket-sized format while replacing cartridges and removable converters with an internal ink chamber.

To fill the pen, remove the cap at the end of the barrel to access the piston knob, immerse the nib and feed in bottled fountain pen ink, and turn the mechanism to draw ink into the chamber. A transparent ink window makes it easy to check the remaining level before leaving home or beginning a longer writing session.

The body is made from matte black anodized aluminum with a fixed gold-plated clip and gold-tone details. Closed, it measures approximately 4.06 inches long. Posting the screw-on cap extends it to 5 inches, providing a more comfortable length for regular writing.

Choose from five gold-plated stainless steel nib sizes: Extra Fine, Fine, Medium, Broad, or Extra Broad. Kaweco recommends Medium for customers who are unsure where to begin. The pen uses the threaded Kaweco 190 nib unit, developed specifically for the Piston Sport with an additional seal around the filling system. Compatible replacement nib units are sold separately.

The body is made from solid aluminum with a matte black anodized finish. Chrome-plated details include the permanently attached pocket clip and the Kaweco medallion set into the cap. At 4.96 inches long and 26 grams, the pen has a noticeable metal feel without the weight of Kaweco’s brass models.

The defining feature of this version is the larger threaded 250 nib. It gives the front of the pen different proportions from the Original 060 and adds three grams to the overall weight. Choose from Extra Fine, Fine, Medium, Broad, or Extra Broad. Kaweco recommends Medium for customers who are unsure where to begin.

The stainless steel nib is made in Germany and can be unscrewed and replaced later. Compatible replacement 250 nib units are also used by the Kaweco Supra, making it possible to change the writing width without replacing the complete pen.

Original 250 accepts standard international ink cartridges and comes with one blue cartridge. Its longer barrel also accommodates a full-size Kaweco Standard Converter, sold separately, for filling the pen from bottled ink. A thread in the feed secures the compatible converter inside the front section.

The body is made from aluminum with a matte black anodized finish. Chrome-plated details include the permanently attached pocket clip and the Kaweco medallion set into the cap. At 4.96 inches long when closed and 23 grams, the pen has a substantial metal feel without the weight of Kaweco’s brass models.

The 060 designation refers to Kaweco’s smaller threaded nib format, also used across several of the brand’s other fountain pen collections. Choose from Extra Fine, Fine, Medium, Broad, or Extra Broad. The stainless steel nib has an iridium point and can be unscrewed and replaced later if the customer wants to change the writing width or nib finish.

Unlike Kaweco’s compact Sport and Liliput fountain pens, the Original has enough barrel space for a full-size Kaweco Standard Converter. The converter screws into the front section for a secure connection and allows the pen to be filled from bottled ink. It is sold separately. Standard international ink cartridges can also be used, and one blue cartridge is included.

The threaded cap is removed during writing and is not designed to post securely on the rear of the barrel. Without the cap, the pen measures approximately 4.7 inches and is balanced for extended writing. The attached clip keeps it secure in a pocket, notebook cover, or pen loop between uses.

A push button advances the 0.7 mm graphite lead, eliminating the need for sharpening. The lead size works well for handwriting, annotations, diagrams, and sketching, while the broad faceted body provides a substantial grip and helps protect the narrow lead inside the mechanism.

At 37.9 grams, the pencil is intentionally heavy for its size. The brass supplies enough weight to rest against the paper without requiring excessive downward pressure. Customers who prefer very light pencils should take the weight into account before ordering.

The untreated brass changes with handling. Fingerprints, darker areas, scratches, and polished sections gradually form an individual patina across the body. These changes are expected and will differ according to how the pencil is used and stored.

Silver-tone details include the Kaweco logo cap and push mechanism. The pencil accepts standard 0.7 mm mechanical pencil leads; Kaweco offers HB graphite refills in packs of 12. An optional Sport clip can be added separately for attachment to a pocket or notebook.

At 41.6 grams, this is an intentionally heavy pocket pen. The weight gives it a noticeably different feel from plastic and aluminum Sport models and reduces the amount of downward pressure needed while writing. Customers who strongly prefer lightweight pens should take the weight into account before ordering.

The brass surface will change through use. Handling gradually darkens the metal and introduces marks, tonal variation, and polished areas where the pen is held most often. This natural patina is expected and will make each pen increasingly individual over time; it should not be treated as a finish defect.

Silver-tone details include the Kaweco logo cap and stainless steel nib. Choose from Extra Fine, Fine, Medium, Broad, or Extra Broad. Kaweco recommends Medium for customers who are new to fountain pens, while Extra Fine suits compact handwriting and Extra Broad produces the widest standard line. The threaded 060 nib unit can be replaced later without changing the complete pen.

A push button operates Kaweco’s heart-curve mechanism, engineered for a controlled action without the sharp clicking sound of many retractable pens. The 36.4-gram body supplies noticeable weight against the paper, reducing the need to press down firmly while writing. Customers who prefer very light pens should note that this model is intentionally heavy for its size.

Handling gradually changes the surface of the brass. It will darken, pick up marks, and develop an individual patina according to how frequently the pen is used and stored. The changing finish is part of the design; the pen will not retain the brighter appearance of unused brass.

Silver-tone details complete the body, including the Kaweco logo cap. A removable clip is not included, but compatible Sport clips can be purchased separately for carrying the pen on a pocket or notebook.

The pen arrives with a blue 1.0 mm D1 ballpoint refill. The refill meets the ISO 12757-2 document standard and can be replaced with widely available D1-format refills. Kaweco offers black and blue refills in several line widths, along with additional specialty options.

Closed, the pen measures only 4.2 inches long. The screw-on cap can be placed on the back of the barrel for writing, extending the pen to approximately 5 inches. Its acrylic construction keeps the weight to 13 grams, while the permanently attached gold-plated clip secures it to a notebook, pocket, or pen loop.

Choose from five gold-plated steel nib sizes, ranging from Extra Fine to Extra Broad. Kaweco recommends Medium for customers who are unsure where to begin. The threaded nib unit can also be replaced later, allowing the pen to be adapted to a different writing style without replacing the complete instrument.

Art Sport accepts short international ink cartridges. It can also be used with bottled fountain pen ink by adding a Kaweco Mini Converter, sold separately. One blue ink cartridge is included, and the pen arrives in a Kaweco tin box.

The ballpoint pen is made from aluminum alloy and weighs 22 g, light enough for longer writing sessions without feeling flimsy. A heavy-duty spring gives the click mechanism a firm, deliberate action. The pen uses a Schmidt P900M refill; HMM’s individual Ballpoint page identifies the refill as 0.7 mm black ink and notes Parker-style refill compatibility.

The second piece is a 101 g aluminum paperweight with HMM’s 12-facet geometry. The hollow center turns it into a pen holder, keeping the ballpoint upright and easy to grab while also giving loose notes or small papers a place to stay put. It is a small object, but it does useful work on a desk.

Choose Black for a darker, more graphic set, or Raw Aluminum / Silver for a lighter finish that shows more of the metal character. The set arrives in a gift package with a paper inner structure designed for the pen and holder.

Its size makes it easy to carry, but it doesn’t feel compromised when used. The rounded aluminum body has a quiet weight in the hand, and the magnetic tip system allows you to switch between graphite and the Eternal tip without ceremony. It’s the kind of pencil you keep nearby rather than put away—used often, noticed less, and valued for how naturally it fits into everyday work.
