For this test I chamfered some pieces of talonite (Cr/Co superalloy).
Chamfered a cutoff steel for a lathe (unknown HSS, correctly hardened).
Then I went on to thinning and sharpening a Kurosaki in SS/R2 and an Akifusa in SRS-15.
I saw no real difference on the talonite, maybe the kunsuto/hibiki/king were slightly slower.
On the HSS cutoff steel I think the shapton pro and the chosera was the fastest. The hyper and glass were very fast too, no big difference really.
Is there a winner stone here? Not really. They are all quite different though.
On rs/srs-15:
Kunsuto
Feels a bit rough.
Not the fastest, medium speed.
So so contrast.
-------------------------
Chosera
Feels quite smooth but effective. Not super smooth though.
Fast.
Quite good contrast.
Good polish on edge.
-------------------------
Hibiki
Feels very smooth and refined.
Medium/low speed.
No contrast at all.
Good polish on edge.
This stone is probably finer than 1k.
No pic here. Nothing to see!
------------------------
Hyper standard
Smooth and nice, maybe mixed with bit gritty feeling.
Seems quite fast.
Quite dark contrast. But with silver scratches just like on carbon.
---------------------------
Shapton pro
Feels rough/very rough but effective.
Very fast comparatively.
Light gray contrast, very consistent finish, similar to chosera.
---------------------------
Glass
Feels smoother than the pro but not as smooth as the hibiki.
Cuts about as fast as the pro.
Could produce same contrast as pro but could also completely remove it I found. Very hard to get repeatable results.
Here you can see how it can look. 1 side quite dark and next to it contrast gets removed.
