Anton, WELCOME to the Yard! I don't think you will find much about the HT of the BusseKin blades. They're kinda closed mouth about it, as it's just ONE of the things that make their blades so outstanding and allow them to offer such an IRON CLAD warranty.
I'll try and find something for you and post it up in this thread. give me a few minutes but I might well already be something you have seen.
