This thread reminds me of when I first started getting into knives.
The steels you name are interesting because they're all very different. You have a spring steel, a ball bearing steel, a high-alloy tool steel, and a cutlery-specific high-alloy stainless steel. To me that suggests you're not really sure what it is you're looking for in your steel choice.
With daggers cutting ability is always more limited by nature of the grind, as the bevels must be steeper than a single-edged knife of the same blade width or height, or the radius of a hollow grind must be smaller. Both of those things impede cutting ability. Plus a reinforced tip further exacerbates this problem by usually being thicker or more obtuse on the edge reaching the point. Can such knives cut? Yeah, a bit, but they will not cut very well.
The best cutter among daggers will probably have the widest blade, which will allow for the best cutting geometry.
The blade length you're looking for is also uncommon, as 4"-8" blades are the most common among production or midtech daggers.
You would almost certainly need to get a custom knife to tick all the boxes you're looking for in the same dagger.
