Garolite Sheet G10. Fingertech Robotics; This G10-FR4 garolite sheet made of glass cloth impregnated fiberglass-epoxy resin is extremely high strength and available in black, green, blue, red and orange. Both use resins that can give off toxic compounds when heated, even friction heated by a saw blade. As noted, the fiberglass in G-10 is very hard, and ruins steel blades in a hurry. The best way I have found for cutting shapes out of sheet stock is a Rotozip tool with a tile bit. Do it in a well-ventilated area and use a good respirator. Coloured G10 can look fantastic on the right project. An incredibly strong material G10 is the material of choice for hard working and heavy duty knives. G10 liner material eliminates the hygiene and swelling issues caused by vulcanized fibre. G10 can be sand blasted to create a fantastic textured finish.
