I've said the same about strength in at least a couple of places recently. My worst knife experiences have been with soft "tough" steels rolling over at the apex.You are making 2 questionable assumptions and I think this is why you keep on saying that MagnaCut should be run softer.
1. Uses differ. In some applications you would be correct that MagnaCut should be run softer for improved toughness. In other cases it should be run harder. You are making an assumption that harder MagnaCut won't work for your use, but you haven't used it so I am not sure why you think it is not tough enough. It is tougher at 63-64 than Vanax at 61. I don't know if it is tougher enough for you, but neither do you.
2. You are making an assumption that MagnaCut is being treated harder for improved wear resistance, but I doubt that's the case. In the majority of cases MagnaCut is run harder not to increase wear resistance, but to increase strength, resistance to deformation. Higher strength with still good toughness has benefits outside of higher wear resistance. Higher edge stability is always preferred, since deformation is as or more difficult to fix as microchipping and deformation can cause more dulling than chipping. MagnaCut is in the middle for wear resistance, but it has the best balance among all the attributes.
Great balance of all the properties is the best quality of MagnaCut, It is a very flexible steel and can be used in a variety of roles. In thin kitchen knife edges you want higher hardness so that you can have more acute edges for example. Same with small knives. MagnaCut is an extremely well balanced steel that can and should replace a bunch of other steels used today. It will not replace all steels since for some applications other steels are better due to their properties.
Staying with the OPs theme, I am sick of people thinking that there is a magic hardness number MagnaCut should be run at. Some say it should be softer, some it should be harder when in reality it depends on the application. In addition I am sick of people that have never used it making judgement calls and giving opinions and recommendations on how and where it should be used and in what condition.
If you're cutting jelly rolls or tape, then hardness doesn't matter at all. What magnacut provides at 63 hrc is an apex that is unlikely to chip, break, roll or otherwise deform during normal use.
That is also a form of real world edge retention.
