I had a Hattori Hanso 240 gyuto forged with a Thor hammer from 1000 layers of vibranium and adamantium damascus with a glowing laser etch finnish, a unicorn horn ferrule and the heart wood from an ent tree wa handle. It had the cutting performance of the thinnest laser with the food release of a monster thick spine workhorse and an original KS profile. You never needed to sharpen it.
Sadly I sold it a long long time a go in a galaxy far away. If you want to inquire the present owner if his willing to sell it to you, I can give you the contact info of the mental institute I sold it to. PM me for the info.
Or you can email Hattori Hanso if he'd like to make another one for you? You can find his contact info from Quentin Tarantino or Uma Thurman. Just tell them I sent you.
