On demand; steel talk!
My favourite steels are, as many of you know, aeb-l and uhb20c. They are both fairly low alloy, super fine carbides. With the right HT, these are the steels I like best to use myself. And general feedback is that they do provide a very good mileage.
But this is indeed very much a personal preference. Depending on the user and sharpener. Maybe these steels are better for the way I use a kitchen knife, with a fairly light hand, and a low angle highly polished edge. As soon as I don't have razor sharpness I will hit a strop, and these steels work well for that. Sharpenability is important to me, and fine edge stability, as I like a thin edge.
I have tried alot of other steels and can say that for me, the higher alloyed with larger carbides and wear resistance, isn't for me.
I do however custom make, so if you know what you want, let me know and you'll get a time and price. Sourcing steel is no trouble, but you'll be paying the extra cost since with aeb-l and uhb20c I buy in large quantitys to get a good price. And really to get a superb HT is about care, so I'm fairly confident you'll be happy, if you know you like a certain type of steel grade.
Easy for me to source locally; any tool steels(sld-d2/skd-a2/O1/highspeed vanax like m4 etc..), uddeholm have their versions. Elmax, rwl34 (like cpm154), damasteel.
