Any recommendations for hard mousepads that aren't fuckhuge? With rounded/chamfered edges too, preferably.

I tried this POS in picrel and it sliced open my pointer finger with no issue, simply from trying to reposition it on my desk. The plastic on top of the rubber is so damn thin that I don't think sanding it down will even help prevent it from cutting me again, and I'm not keen on taking sandpaper to it and having scuffs all over the edge of it. Ideally around the same width, 340mm x 280mm (or 11 x 13 to 14 inches)
