Paul like you, I too enjoy the spiral blades. I really got to where I wanted to learn them when I was at your house and saw all your wonderful projects made with the spiral blade. I now like them the very best and it really did not take me that long to learn. It was very apparent to me that really delicate fret work is crying for the spiral and it saves a lot, and I mean a lot, of worry about possibly braking some delicate pieces when one is cutting. They are so much quicker and way easier on the extremely delicate fret. Thank you for that, my friend. You taught me well just by letting me look through some of your very well done fret work.
