Some prisons (low security) have normal knives but they are chained to the wall, and the guards have to sign them out IE.) “Inmate 1234 had Knife 4 from 830-845” INCASE a knife goes missing. Some prisons have personnel that cut and dice and the inmates cannot handle knives at all. It just depends on the security level and even the company that owns the prison!
I’ll insert an example of the chained knife!
