As I "guessed" that well known Morihei 3k Green is actually Imanishi 3k Green. Imanishi 3k green is lower grade version comparing to Imanishi 3k White (higher grade, mixed a lot of abbrasive materials, but also much more expensive). But they are both not hard. For me, they are a bit soft. Sometimes my edge bites into stone surface a little bit (see the 5th pic). Morihei Fire 4k is harder as I tested. I don't have such problem.
Below pictures show both 3k performance on Shirogami#2 sharpening with the same number of passes, same pressure and same angle. As you can see Green doesn't really "produce" black metal material. You know it's just white 2 steel! White is much better.
