I have a question about the writings on a knife

[Crd]

Hi,
I want to give away a knive and i thought i would be nice to also be able to explain what all the writings mean.
Could somebody help me with this?

I know that in pic two the writings in the box have something to do with "warikomi" but i couldn´t deciver all of it. (This is also something one can see when looking at the blade )
But other than that i am clueless..

Thanks in advance.
