Conclusions and Summary
The development of H2 seems to have occurred by necessity because of availability rather than a need for improving its properties, though that doesn’t mean that the properties can’t be improved, of course. Overall I expect the properties between H1 and H2 to be similar. H2 will maintain the very high levels of corrosion resistance and toughness of H1, and also its relatively low hardness and wear resistance. The most interesting question to me is whether H2 achieves the same level of hardness as H1 or if it has dropped by a point or two on the Rc scale. We will see as knives are released.
