That would be dependent on what steels, it can take a lower edge than S90V, but requires a more obtuse angle than 13C26, assuming you want a high polish.... it can't be taken down to very acute sharpening angles and that it needs a more obtuse angle at the final edge than others.
That would depend on what you are cutting and how. It certainly is not a steel designed to a high polish because carbides directly reduce edge stability.Some say that the steel needs to have a very highly polished edge.
That is a fairly obtuse profile, I would be surprised if any cutlery steel had problems with durability in that profile in that size of knife.Then I used a Lansky system to reprofile it to the 17 degree slot and then a final edge using the 20 degree slot. I polished the edge using 1500 grit wet or dry sandpaper on a mousepad. OK so far.
