He confirmed that as well - that Hitohira confirmed the same that OS sharpensAnd since most if not all these Morihei's are being wholesaled through Hitohira onto their 'partner' retailers in the West and Singapore, I wonder why they would pass on this info if incorrect or unverified.
I have owned three Hisamoto’s, 2 FFand 1 regular finish. Both FF’s have much better than average bevels and finishing, just a few slight low spots, nice rounding on the spine etc.Another thought. I don't know how Morihei chooses the knives that are getting FF treatment. They might choose the better ones so that the FF treatment process would be easier. Or they might choose the worse ones because those ones are too bad to be sent to customers without any treatment. Or maybe they choose them randomly.
