I wouldn't try to cut up boxes with them but no problems getting sticky (I cut open juice boxes with scissors and they always end up sticky after a few times).

Maybe I got a bad pair or they fixed the problem of the center screw loosening up, so sick of fixing it every time i use them and its finally jammed it a not at all tight position

They also wash very easily and I have had zero problems with them rusting or with the fastening screw loosening

My daughter and I have a weird problem.
