These are an absolute staple when it comes to my work. They have a natural texture so that you won't get a super smooth finish, but in some cases, that's extra helpful. I use these to poke holes, smooth surfaces by rolling and add lines for my wood grain pieces. Most people have something like this lying around the house already, and if not they're super easy to get. I reuse my chopsticks from takeaway and have had the same wooden skewer for years now. If you need a flatter end or a finer point, you can easily use a piece of sanding paper or an X-ACTO knife.
