I would like to just announce how much I f7cking love my morihei hisamoto right now.. end game knife has been found.
I'm not a pro but in a similar boat with my 300 from Tsubaya. The steel is unreal too. Unlike yours I love it because it's such a beefcake. Still very thin behind the edge but it's 430g so it thickens up quickly. Nothing about it makes sense but it just works for me. I'm so close to buying the 270 morihei on hitohira but am concerned it won't have the same magic as this one. I previously had a 210 morihei and it was good, but not on the same level as this one.
