Compare the thickness of KAI to that of Perma-Sharp Super. If there is no big difference - strike me blind and call me Charlie.
Hi Charlie
I don't have them so I can't be 100% but I have been measuring every blade I ever tried (70+) and apart from counterfeit Lords I never ever found any modern stainless blade that was not 0.10mm thick. The same thickness doesn't mean the same stiffness though; there are numerous stainless steels to choose from and even when they are the same different companies will use different heat treatments with different outcomes.
