Since we recently received the Kaweco pens in extra-fine, fine, medium, and broad nib sizes, I thought it might be helpful to do a comparison writing sample.
I enjoyed writing with all of the nibs. They are all smooth (with some feedback) steel nibs, with a smooth and reliable flow in all sizes. There’s not a huge difference between the extra-fine and fine nibs. There is a noticeable difference between fine and medium, and a huge difference between medium and broad.
The Kaweco nibs are identical on the Classic Sport, ICE Sport, and Al-Sport, so you can expect these will be consistent across all of these pen models.
Right now only the medium nibs are imported regularly into the US from Germany, so we had to place a special order for the rest of them direct from Germany. Because of this, we may be out of stock of certain nibs more than usual due to the long shipping time (but we will try to keep them in stock!).We have the Classic Sport, Al-Sport, and ICE Sport available on our site.
