Good pictures. Next time you break on put some pieces of hard wood between your vise jaws so that the blade isn't bending across the sharp edge of the jaw.
Other than that, raise the temp of your oil a bit, about 90 - 100 F. You mentioned non-mag, be sure you're seeing non=mag on the way up, catch it when it first gets there, don't let it go past and then try to bring it back down. Once you have it put the blade back in the forge for a short time. Hard to say exactly how long as the mass of your blade and the temp in your forge are unknown but likely somewhere between 15 seconds and maybe a minute. You want the steel to be about 100 - 150 degrees beyond non-mag when you quench.
Try that a few times varying the specifics and see if you can get a light grey color with very fine grain and not so much lumpiness. Should bend some and then break like glass so wear eye protection...
