Sorry for the vague question, I meant the youth in recent years. Edited it in my original post.
But maybe still a follow-up question; I read somewhere that it was tradition to pass on swords (especially the long samurai swords), does this also apply to their striking knife after the seppuku?
seppuku was used either voluntarily by samurai to die with honor rather than fall into the hands of their enemies or as a form of capital punishment for samurai who had committed serious offenses, or performed because they had brought shame to themselves
