Greetings from Melbourne, Australia. I trust all are well during these challenging times. I have just purchased a Robert Sorby 3mm Bead Forming Tool and am itching to try it out. Before putting it to work I am wondering what is the preferred method to sharpen the tool. I have spent some time on the Internet last night but there seem to be some conflicting approaches to sharpening similar tools. Can you please steer a novice in the right direction?
