This will be short .
Do you have a good self healing cutting mat ? Great . Now sometimes we need something really hard to cut on. What do you use ?
I have two go to surfaces for this . One is a piece of TEMPERED glass from a salvaged Stereo tower door. The other besides my mat ? well , it's a sample of a counter top .from Home Depot . It is great for this .Also both allow a totally level cutting surface .
You can use a piece of marble too , or a sink cut-out from a countertop . I have a work surface that is over 38 years old .It is a vanity top made from Corian . It's frost white in color and very durable .Every two years I take the palm sander and clean it off . It gets some cut marks on it from time to time .Paint and glue too .
You can sand Corian then ,Polish it to a high shine if you like . I don't polish mine when I am finished dressing the surface with 600 grit wet-or dry paper .
This way I get no glare from the surface. It's heavy , but portable and there have been times it sat on a wooden T.V. Table as my workspace . Ah the open road .Yep , I even modeled when on the road in our fifth Wheel . That was before the Toy Hauler with a rear Garage ( Shop ).
Good luck . T.B.
