What the Kaweco Classic Sport actually is

It is a short pen that becomes a normal one. Capped, it measures 10.5cm, so it disappears into a coat pocket. Post the cap on the back and the pen reaches about 13cm. Kaweco's spec sheet puts it at 12.7cm open and 13mm across the barrel without the clip. On the scales it is 10.7g.

The barrel is octagonal, and that shape does two jobs. First, it stops the pen rolling off a sloped desk. Second, it gives the flat cap its faceted look. So the design has survived a century almost untouched.

Kaweco make the pen from plastic rather than metal. Purists grumble about that. But the plastic one is the light one, and it costs under thirty pounds. Kaweco say the pen and its nibs are made in Germany.

The 1911 date, and why shops say 1934

Almost every stockist dates the Sport to the mid 1930s. Choosing Keeping, for example, put it at 1934. They describe a pen sold for the use of "ladies, officers and sportspeople". That phrase is real. The date attached to it is not quite.

Kaweco's own history page puts the same three groups in 1911. Pocket fountain pens for ladies, officers and sportspeople, it says. Then it calls that moment the birth of the Kaweco Sport. Their product copy repeats it: "in 1911 something remarkable by the name of Kaweco Sport was created".

So the name and the idea are Edwardian. The octagonal plastic pen most people picture came later, in the 1930s. By then the Wiesloch firm Knust, Woringen and Grube had bought the Kaweco name. None of that changes how the pen writes. It does mean a shop assistant citing 1934 is telling you half the story.

Nibs, ink and the converter question

Kaweco offer five nib widths on the Classic Sport: extra fine, fine, medium, broad and extra broad. They recommend medium if you are unsure, and medium is the width UK shops stock deepest. The nib itself is gold-plated steel with an iridium tip. It unscrews as a single unit, so you can replace a bent one at home.

The pen ships with one blue cartridge. After that it takes standard international short cartridges. Those are the cheap and common kind, so you are not locked into Kaweco ink.

Bottled ink needs one extra part, and this is where people get caught. Kaweco sell two converters, and only the smaller one fits. Their converter page states it directly. The Mini converter suits the Sport and Liliput ranges. The Standard converter is for the larger pens. Buy the wrong one and it simply will not go in.

Where to buy it in the UK, and what it costs

Three routes are worth knowing. The cheapest is not the nicest.

Check the black Classic Sport at Choosing Keeping

Amazon is cheaper by about five pounds. Choosing Keeping, though, is a proper stationery shop on Tower Street in Covent Garden. There you can hold the thing first. Their free delivery starts at £100 and covers mainland UK only, so a single pen always carries postage.

Kaweco's own site also lists white, red, green, navy, bordeaux and a guilloché black. Black remains the one to buy. Against black, the gold nib and the gold script on the cap actually read.

What it is good at, and what it is not

It is very good at being carried. The cap seals well and the pen weighs almost nothing. The octagon keeps it still on a desk. As a first fountain pen it is close to ideal. Nothing about it is precious, and every part is replaceable.

It is less good in a large hand. Unposted, the Sport is genuinely small, so most people write with the cap on the back. The plastic also scratches. Gold plating on the clip wears through on a pen carried in a bag daily. Neither is a fault exactly. Both are the price of a pen that costs less than a takeaway for two.

Anybody buying for a designer should also look at our designers gift guide. It starts where this pen stops.

Kaweco Classic Sport FAQs

How much does the Kaweco Classic Sport cost in the UK?

£27 at Choosing Keeping and £22.29 on Amazon UK, both for the black pen with a medium nib. The extra broad was £21.50 on Amazon. All three were checked on 5 September 2026.

Which nib size should I choose?

Medium, unless you already know otherwise. Kaweco recommend it themselves, and UK shops stock it deepest. Fine suits small handwriting and cheap notebook paper. Broad and extra broad are for people who want the ink to show.

Does the Kaweco Sport take a converter?

Yes, but only the Kaweco Mini converter. The Standard converter is built for the bigger pens and will not fit. Without a converter the pen runs on standard international short cartridges instead.

Is the Kaweco Classic Sport made in Germany?

Yes. Kaweco state that the whole pen and all its nibs are made in Germany. The company has been in Heidelberg since 1883.

How big is it?

10.5cm capped and about 13cm posted. The barrel is 13mm across without the clip, and the pen weighs 10.7g. Those are Kaweco's own figures.

Is it a good first fountain pen?

It is one of the best places to start, mainly because nothing on it is expensive to replace. The nib unit unscrews and cartridges are the common international kind. The pen costs about as much as a paperback and a coffee.

What is the difference between the Classic Sport and the AL Sport?

Material and weight. The Classic is plastic and costs under £30. The AL Sport is machined aluminium and sells for roughly three times as much. Both share the same octagonal shape and the same nib units.
