They are both one side open, one side closed in stainless steel. I see the shavecraft at a cheaper price point, but what's the difference between the two?
Are you sure? Whole aluminum razors weigh approximately 38 grams, head and handle. Just weighed an aluminum Apollo SB 2 piece and it was this weight. The Ikon 101 head alone weighs 34 grams and I don't think it is aluminum or pot metal since it is not plated. So that leaves steel, silver, gold, or some other heavy metal.
