Often people who use fountain pens like converters because they allow you to use bottled ink. For a long time, people who used the Kaweco Sport didn’t have a converter that could fit in its short barrel, only having touch-and-go luck with a short mini-converter from Monteverde. Earlier this year Kaweco released a “squeeze converter.”
I have heard many times people saying something along the lines of “I can’t quite seem to fill this converter all the way” or “this converter sucks.” There’s a bit of a trick to using it effectively.
It’s easiest to use the squeeze converter with a full bottle or a wide bottle, or at least not the bottom bit of a tall ink bottle like Noodler’s, because you need to squeeze in the middle of the converter rather than twisting the top of the converter – you might have some problems squeezing if your fingers are stopped by the mouth of the inkwell.
The first step is pretty self-explanatory. Stick your nib and section into the ink and give it a good slow squeeze or two or three. You should see some air bubbles or maybe hear a little suction.
You may think it is empty, because there doesn’t seem to be anything in the converter.
However, turn it upside down, and give it a few firm taps or careful shakes. You can try tapping the converter against your table. Some ink should fill the end of the converter.
Squeeze again, but very carefully, to release the air in the converter. Be careful not to squeeze too fast, or you might spurt out ink that was in the feed. You should hope to see some air bubbles coming out at the breather hole in the feed.
Stick it back into the ink while squeezing and release, sucking up more ink.
If you give it a tap again upside down, you should hope to see more ink! Repeat as needed, and wipe off the section when you’re done.
It will be very difficult to both get or tell if you’ve gotten 100% fill. It’s much easier with the piston fillers because the entire tank is clear so you can see. However, if you’ve gotten it basically full, you should be good to go.
While it’s not the most easy-to-use converter, with a little practise, it’s Kaweco’s answer to getting the Sport to use bottled ink without a syringe or eyedropper.
If all else fails, you can always live life on the edge.
