Thanks for finding the H1. I was not aware that the price on this type of steel had come down to the point it was afforable.
There are a lot of great materials out there but if nobody is buying 1000's of tons a year for some mundane product like razor blades they are too expensive to even consider.
It's like the high tech fibers we use on boats. The reason we can afford them is they make tires out of them.
