The Shapton Glass 16,000 grit is the ultra-fine end of the Shapton Edge Pro lineup - a polishing stone rather than a sharpening stone. At this grit you are not removing meaningful metal from the edge; you are refining the scratch pattern left by coarser stones and bringing the apex to its finest possible state. Shapton Glass stones are slow-wearing and splash-and-go - no soaking required, ready to use in seconds. At 25mm wide and 150mm long the dimensions match the Edge Pro system exactly, and at 6.5mm thick they provide good working life even with regular use.
A note from reviewers: at 16,000 grit the stone may not produce a clearly visible mirror on all steels - harder stainless and carbon steels respond better than softer alloys. The 8,000 grit often produces a more dramatic visual mirror on many steels because the scratch pattern is deeper and more uniform before it is refined. The 16K is the right choice if you want the absolute finest edge and are comfortable reading the results by sharpness rather than appearance. Pairs naturally with the Shapton Glass 8K as the previous step in a finishing progression.
What Customers Are Saying: Five reviews averaging 4.5 stars. One reviewer notes the 8K produces a more visible mirror on most steels but considers the 16K a nice polishing stone regardless. A second reviewer calls it a very nice stone for polishing. A third is still experimenting with which steels benefit most at this grit level - a fair observation for any ultra-fine polishing stone.

The 500, 2K, 16K set puts the perfect mirror edge on all my knives. Very easy to use - just a few drops of water and they're ready to go. These have brought new life to my EdgePro system.

Fantastic stone, and worth trying, but I am having the same issue I have with the EdgePro 6k polishing tapes. The Shapton Glass 8k stone gives you an absolute mirror polish, just like the Edgepro 3k tape, and the 16 K brings the polish up even higher, again like the 6k tape BUT, the 16 k stone will make scratches on your edge more visible. With the EP 6k tape, I would only use it on some steels. High grit stones can be difficult to work with in this way. It may seem as though the polish gets worse with this stone, but in fact it is getting so much higher in polish, that you can now see scratches from your coarse stones used when you set the bevel. I find certain steels look better than others with this stone. Great feel on the machine though, buttery smooth!
