I never used 52100 myself as I always thought it was a steel for forging as so many knife forgers use it. I just thought I'd chime in that Data stats are for industry as the guys above have pointed out. I just wanted to add the data sheets are almost universally for much thicker material than knives. The soak for one hour per inch of thickness is a clue. You're making a knife at let's say 1/8" thick, that would mean you would only soak the knife for less than 10 mins and of course as the guys above said that will not be long enough. The 1475 is also the sweet spot for O1 as well. So now you know why experienced makers tell you to experiment as the data sheets have a different target than knives, especially tool steels. It doesn't hurt to ask and I didn't know that the HT for 52100 was pretty much the same as O1 a steel I am familiar with. I learned something as well.
