By inversely proportional, I mean that given any particular knife or steel - as you make it stronger - it will become less tough. Or if you make a steel tougher you are making it less strong (You cannot increase one without decreasing the other). It is impossible to have both at maximum - that would be the perfect steel. Infi is great and it is strong and tough but to go along with what I'm saying - if they tried to make it tougher - it would invariably lose strength. And, if they tried to make it stronger it would lose toughness...make sense?
I understand.. but each steel has a hardness where toughness and strength are at a higher ratio to each other (I guess?) than at other hardness's... not that BOTH are MAXIMIZED. maybe at 60 RC a knife has high strength and pretty low toughness... but at 58 RC the strength is slightly compromised, while toughness is now way better.
