I kind of think that what you are after is going to involve a lot of compromises - Prybars need to be blunt, thick, robust and a little softer than knives where they are usually thinner need better steel and saws (if they are really to saw not just notch wood) need a different profile altogether.

I might be tempted to prioritise the tasks and think around the top 2.

Or I might be over thinking this....
