I'm somewhat confused about the type of treatment that the SOG knives get at the factory, primarily the Seal Pup Elite. The steel used is AUS 8 which is a decent enough steel but with my Elite the steel seems to hold an edge better than other brand knives using the same steel. SOG says that they Heat Treat, but they also say that they Cryo Treat. I would think that each would change the structure of the steel in different ways. Does SOG use one or the other or do they use the treatments in combination with each other? Just wondering due to the awesome performance of the AUS 8 used by SOG. Thanks in advance.
