Finally have enough natural stones to be considered a "collection." I played around with them today, alternating scratch patterns at different angles to keep track. All are in the medium range:
- Tamba Aoto purchased from MetalMaster in 2013
- Ikarashi purchased from JNS in 2016 (yes, I'm lazy and should flatten it more thoroughly)
- Vintage Numata of unknown origin picked up on BST last month
Considering how hard and un-muddy the Aoto is, I was a little surprised to notice I had to go down to a GS500 to remove all of its scratches. At the same time it gives the shiniest polish, and seems like it has the widest grit range.
The Ikarashi was about what you'd expect from the forum chatter. Scratches were removed by a King Neo 800, the highest grit synthetic I have at the moment. Pretty middle of the road, maybe I'm just not a fan of how weird-feeling and chalky it is.
The Numata is the finest of the bunch, supposedly a vintage stone from a finer vein than modern Numatas.

I like these mediums because they give a nice useable edge. They're all on the harder side, which seems to be my preference. Lord help me if I get the urge for a finishing stone, the medium range is enough of a rabbit hole for my taste (do I need an Aizu next?)
