I definitely see some paper caught in my knives after shredding newspaper, but I pull the worst off right away (it tends to build up primarily at one end) and I assume the rest gets cleared off by the cardboard I shred because it doesn’t seem to stick around.I bought a paper shredder to make bedding from the newspapers we get weekly. But the machine got stuck after a month. The thin paper winded around the knives.
(As I have mentioned in earlier posts, I have a pretty heavy-duty 16-sheet shredder so that I can shred corrugated cardboard boxes.)
