Larrin has tested LC200N but I think it was under name Z-finit. For stainless steel, it has superb toughness.
H1 is a different animal and you can't test it the same way. You can't get it outside Japan and you can't heat treated it - it just not work that way. There are no bars of H1 available for knife making. And for toughness testing you need to have speciment with specific dimensions.
