So, performance wise, you will see no improvement over what you have, except the 12K.

The Chosera 1k is the Gold Standard, especially over the King, performance is the same though, I’d wait and buy the Chosera 1k, you will not regret it.

As far as the others, I have them all and still use the 4/8k combo stone on every razor. The 8K Norton is tough to beat.

I did recently buy a Nubatama, 1k and have the 4k on order. I love the 1k, it is fast and does not load up like the Chosera and surprisingly leaves a shallow scratch pattern.

I will see how the 4k works over the Norton, but will still keep the Norton 8K.

I would do a 1, 3-4, 8, 12K progression. You could do 5k but the low grits are where all the heavy lifting is done. The job of the 3k is removing deep 1k stria, you may find yourself spending a lot of time on a 5K.

It is exactly why I am going to the Nubatama, for a more aggressive stone for 1k stria.

Soaking is not an issue, just fill a plastic shoe box with water and drop in the stones, everybody in the pool, while I get everything else together, then lap all under running water and leave the Norton and the Nubatama in the water.

Use a squirt bottle, (old shampoo bottle) instead of a sprayer and hone on a rubber stone holder for height, on a fast food plastic tray to catch all the water and swarf. A squirt bottle gives plenty of water to keep the stones wet and wash off swarf.

If it were me, I’d buy the Chosera 1K and the 12k Super Stone… and with the Norton 4/8k, wear them out.

Meanwhile, save up for the 20k SG…
