I have recently gotten a few Hindostans to test out and they have really won me over. They may be my favorite all around stone at this point, and I've tried quite a diverse spectrum of stones. They fit into such an interesting and useful range, being able to both do earlier level fast metal removal and go all the way up to a razor finisher. Coticles can of course do a similar range, but I find the Hindostan lends itself easier to it and doesn't have as much fickleness about it. The price is much better as well!
I'm sure not all have such range or are coarser - the three I have so far have all been similar performance and are the finer variety. Very much what people look for out of Aizu stones the Hindostan delivers when refreshed often (it needs to be refreshed more than an Aizu by comparison) but has the ability to really take things further.
Of course, an Aizu has no hope of actually finishing a razor whereas the conditioned surface of a Hindostan can, so they are certainly different beasts. Usually, Hindostans do not seem to be lookers and unfortunately a great deal of them have been used with oil and degreasing them turns them even more bland looking. The third one I got and I attached pictures of is a beautiful example that wasn't used with oil. Actually, I'm not convinced it was ever used at all besides being banged up in storage over the years. Thus far I haven't seen another Hindostan like it, but maybe more used to look this before oil and degreasing - who knows. Wet and dry picture. Slurry comes up a very nice pink and it has a very nice smell to it!
Wow, I've never seen a stone like those photos. How certain are you it is a hindo? I dont think they often have so much color, mine dont atleast. Does it have sediment lines on the side?
I like my hindos alot also
