The Steel Heart E has quickly out-paced the Straight handled Steel Heart II in sales. I believe it appeals to a much larger market than did the straight handled version. We do not currently release specific production numbers on any of our standard models but it should be noted that the straight handled versions have had quite a few years head start on the "E" models. Nonetheless, the "E" models will soon be catching up in total numbers.
Yours in unclear. . . errrr, I mean "nuclear" numbers,
