When will there be new boxes with knives for GP?

Hello!
Sorry for my language, I'm from Poland.
My question is about GP currency.
Some of this currency has accumulated over a period of time and I have nothing to spend it on. I have been waiting for a long time for GP case updates. If any show up, it's only weapons. I would ask our Technicians / Administrators to add knife chests. Something that will change weapons that are covered with 5 sides. Thank you in advance for considering this situation positively. Regards!
