I would be astonished if the Henson clone was machined within the nominal standard of the actual Henson razor. Henson uses machines that are capable of 5 ten thousands of an inch (and better). Their CNC machines cost multimillions today (not when they bought them years ago, for their aerospace projects). I cannot believe that a Chinese hack shop has machines capable of the Henson machines. IMHO, there is no razor manufacturer other than Henson, that can duplicate Henson's insane machining standards. I spent nearly 50 years in the aerospace business, and I know from first hand experience what tight tolerances are all about. IMHO, those manufacturing and finish tolerances make a difference in the razors performance and longevity.
