G10 is a composite material that\’s made by layering glass cloth soaked in epoxy. It\’s very popular in the EDC community for knife scales because it\’s light and durable but there are challenges to making it into pens. Specifically, it only comes in sheets and is extremely messy to machine. The natural (jade) color will slowly darken and patina over time while the OD Green should remain unchanged. Also, the texture is prominent right out of the box but will eventually smooth on the high-wear areas.
