I made some covers for my turning tools from PVC pipe. It is durable and can be formed for a snapin fit. Just use a heatgun to form the pipe around the tool . You may have to heat again to get the correct snapin fit. You can round the tip to match the tool or make the PVC curve or flatten to match tools such as a Spindle Roughing Gouge or skew and scraper. By making the PVC pipe longer you can fit it over the ferrell also .
