This is fascinating reading that fills in a lot of gaps I had in my limited knowledge - thanks for sharing!
"Then the blades were put through a secret hardening process involving heat that Strauss had learned while working in an arsenal in Naples, Italy. He shared the process with no one but his family. This process made Strauss skates unusually flexible for their hardness, something that was very desirable to serious skaters."
Aha, so I'm not just crazy for thinking a bit of flexibility of steel is a good thing versus these newer lightweight designs with rigid aluminum frames! Interesting that it says the newer SkateScience blades have a different profile that's similar the old Strauss blades, by moving the "sweet spot" backwards towards the arch.
