Same here.
For 'heavy' sanding, I use a variety of jeweller's files, often used in the way of a chisel, very lightly. And for lighter work, I use various grit 'wet and dry', down to 6,000 grit, finishing with wet sanding, and then polish, if needed, with either 'T-Cut' or a micro-fiber cloth, or both.
I do have some various sanding sticks, obtained from Tesco for a few Pence,, but rarely use them.
