I now keep all my boxes unfortunately, they take up space and I honestly believe that having the box when one sells a knife says nothing about how the knife was treated. I do understand with the more expensive knives with COAs, that the box is a part of the sale everybody wants but I find it fascinating that if I sell a well kept less expensive knife for say $75, most people ask if it comes with the box.
I think I have every box of like 600 . . . that's what crawl spaces were designed for right ? THE PLACE where everyone stores their knife boxes. I mean why else would they make a "space" like that ?

I never sell a knife.
I would easily buy a used knife if it did not come with the box . . . as long as it was a knife I HAD TO HAVE , for one reason or another . . .
hmmmm
I don't NEED to keep my boxes . . . hmmmmmm
OK
. . . although it could be the Japanese thing . They/we enjoy packaging . The cooler and more beautiful the better . . .
Though , as far as I know, I have no significant asian DNA I do look vaguely Asian , so did my Mom , I identify STRONGLY with some Japanese arts/activities/cultural norms (I sincerely hope this does not offend anyone reading this

=as close to a bow as I could find) . . .
that part of me likes cool packaging.
One thing I noticed from when I was a very young child : as my mother would take groceries out of the shopping bags and set them on the table she would turn the front toward's her and look at it ; then take out the next .
What did I gather from this ?
1 ) she held down two part time jobs during the depression while her husband / my Dad was laid up with an incurable bone disease (they finally found a cure) and she KNEW what it was like to not have enough to eat .
2 ) she was enjoying every moment of finally having enough including enjoying the packaging .
