I'd have to agree with you about D2, in my experience it does perform in that middle ground between ease of sharpening and edge holding. For me personally I don't mind sharpening my knives but I don't like doing it in the middle of a chore and D2 works great. I know knives made with the CPM steels like S60V and S90V can hold an edge forever (it seems) but they can be a real b!#@! to sharpen with regular stones. I guess I'd rather have steels that take an edge fairly quick so steels like AUS 8, 440C, 154CM, VG10, and D2 work well for me and seem to be a good compromise. I don't buy any knife made of AUS 6 or 440A (too soft) and I don't have any knives with blades more wear resistant than S30V. I'm sure there are other steels out there that I would like I just haven't tried them yet. Just my $.02.
