>>8485884I bought a 10 buck pair of glass nail files from Amazon a while back and they're so good at removing nub marks I haven't had to touch a piece of sandpaper since getting them.
Though admittedly sometimes they remove the mark a bit TOO well and polish the piece into a glossy shine but it's rarely noticeable and still looks better than nub marks and is a fraction of the work making and using various grits of sanding sticks.
