Kaweco Smokey Grey

 

Ink Review #195

🧾 Description

Ink: Smokey Grey

Brand: Kaweco

Country: Germany

Available: 50 ml bottles or cartridges.

Pens Used: Kaweco Sport (EF/F/M/B/ BB), Karas Vertex FPNibs ultra-flex with ebonite feed.

 

I got a pack of cartridges of Smokey Grey. Boy, I was in for a surprise; it refused to write in both pens, even after priming (Kaweco Sport and the Vertex), until I forgot it for a few days. Moral of the story, if you can’t get a sample, pop in the cartridge and let it be. 

 

Or syringe it., which worked fine in the Lamy Safari. 

If you want to see what the Japanese EF looks like, check @LizEF’s excellent review. 

 

Ink has low lubrication, and the flow is dry. However, with a Medium Kaweco Sport, when the pen finally wrote it was very pleasant, and it’s like an HB pencil, However, with a Lamy Safari Ef, it was yucky and pale, more like 4 nib. 

 

Moral of the story: if you can’t get a sample, just pop in the cartridge and forget the pen for a few days. The ink needs time to saturate the feed. Or better yet, syringe the ink into a converter and prime the feed yourself. Interestingly, I had no problem at all with my Lamy Safari.

In the Lamy Safari EF, the ink felt underlubricated. The flow was dry, the writing scratchy, and the colour faint—like a 4H pencil. But in the Kaweco Sport M, it behaved much better: smoother, and closer in tone to an HB pencil. In the Karas Vertex, however, it was inconsistent—the cartridge just couldn’t keep up with the ebonite feed and the FPNibs flex nib.

 ✍️ Writing Samples (scan)

Normally, I include a Japanese EF nib in the lineup; here I used the Karas Vertex’s Bock EF nib. The colour is darker because of the ebonite feed.

 Note that the Karas Vertex is fitted with an FPNIBS, featuring an Ebonite feed with a very generous ink flow.

I lost my Kaweco swatch, so I redid it again, that’s why it’s repeated twice.

My experience was tainted by the temperamental cartridges. If I’d know I would have syringed it right away. 

 

No fountain pens were hurt in preparing this review. 😉
