I have watched some professionals on YouTube and noticed that they are cutting sharp crevices with the skew. Instead of using the heal as I've always done, it appears that they are using the toe. That appears to be a great opportunity for a serious catch. What do I need to know to proceed with using the toe to round off beads and make the crevices? How serious an accident can I have from trying this? Should I attempt this without a spotter? I am really anxious to your comments and input. Thank you in advance for responding to these questions.
