Knife play is probably one of the most enjoyable activities for me, though I prefer to call it cutting (which is what we do) because the word "play" doesn’t really... fit. When we do it we’re more focused on bloodletting and the pain/sensation that comes from cutting rather than making patterns or just teasing (not that those aren’t interesting). So usually knife play crosses over with blood play for us.
