It will be the same HT as the LC. This is a very durable lath martensite with good edge toughness.
The FK and the EDC get a plate martensite tweak. This reduces the gross toughness, but improves the edge stability.
The purpose of the difference is to obtain the greatest durability and edge retention for the application. A rough use knife needs some ductility to prevent breaking in an extreme impact that a small knife wouldn't be expected to see. Alternatively, a small thin knife needs to support a narrower edge than a large knife would normally see. So there are some subtle differences in the structures formed that are tailored to the knife.
