Sanding Stick 1" width x 11" Length

The paper gets loose after use. I figured it was because the round knob became loose but after checking this is not the case. The paper gets loose and starts coming off the end and the knob is as tight as you’re going to get it without using another tool which would probably break it. I could try to put some sandpaper into the little round grooves on each side that the metal arms go into and glue this in so that the metal arms have something to bite into instead of just the slick plastic which is what I’m suspecting is causing the issue. I like to rate tools by If it broke today would I buy it again and for this one, I would say......NO.
