Hi everyone. How many versions of the E series did SF make? I am mainly asking about the E2E, E2, E1E, E1 and such. The most I know are the HA version, the Satin Grey versions, of which 2 types were made I think. And then there is the one where the body of the E1 and E2 is HA and the pocket clip is screwed onto the head. Are there any other versions?
