Thread: Kamisori experts’ opinion is welcome

I just shaved once with it. It is the sharpest and smoothest razor that I own. For the first time I had the feeling that the hair were cut without the razor touching the skin.
But the difficulty of holding and keeping the right angle during the passes made the shave a bit aggressive.
Maybe if I used the string to the handle I would hold it easier and steadier.

Does anybody know where can I buy this particular string for the handle?
