I have got no beef with you. Your point of view sticks to geological approach. It's OK.
My POV sticking to what japanese woodworkers and razor sharpeners use to call their stones.

The skin and color are similar to my Nakayama Asagi. All of my stamps are long gone too, but who cares...it's a good finisher. Finding a pedigree on a stone can be near impossible, but finding out if it's a good finisher isn't so hard...enjoy your new stone my friend!
Hi Nicolay
Yes you are on the right track. Awasedo is a general term that means Sharpening Stone or Finishing Stone. Tennen Toishi is another but slightly more specific term meaning Finishing Stone and either of these terms can refer to any of the finishing stones from any of the strata, beit Tomae, Suita, Namito, Aisa.

As far as I can understand the word Awasedo ( 合砥 ) is derived from the japanese verb awaseru ( 合せる ) and the word toisi ( 砥石 ).
awaseru ( 合せる ) is japanese for what we call "to strop" or "to hone" ( Of course there are also many other meanings for awaseru, for example to tune, to match and so on )
toisi ( 砥石 ) is for sharpening/grinding stone in general.
Here it is the example when japanese use such a classification:
