I think these may be some of the first finger implants I’ve seen (not including transdermals and finger dermal anchors). They’re 6mm and 8mm pieces on Nobnig (who has quite a bit of heavy work), done by Samppa Von Cyborg (MadMax Tattoo). I think the photos are by Al Overdrive but I apologize if I got that wrong.
PS. If you’re wondering about the title, it’s because as long as those implants are there, punching someone is going to really suck for both people! “This is going to hurt me more than it hurts you!”
