Mike!
Thanks for asking about this! It's something that I've been struggling with as well for some time.
Bruce, I'm looking forward to your tutorial! Something that you might want to consider adding to it, or making another tutorial about is choosing and buying edgers / bevelers. There's a tremendous variety of types and sizes out there, and it's quite a task figuring out which one does what and which to use in different circumstances.
Thank you both!
Bill
