Spyderco keeps their hardness ratings close-to-chest as to keep everyone out of their heads. Too many armchair quarterbacks that "know more" about a better hardness, than who actually use their knives to care about what the actual hardness really may be. They wish for the performance to be the biggest factor of any given steel and not its HRC number. Many numbers can mean many things, but the most important is how the steel got to that particular number, versus the number itself.
How is the Magnacut performing from Spyderco, for those who do have an example? Do you have another example of Magnacut to compare, and if so, how are they alike/dissimilar?
