I have the Ci1 and the Ci0 -- the Ci0 had a learning curve for me -- should have watched the movie.. Now I used it as intended instead of how I wanted to use it... It is a go to tool -- I use it so often I may forget how to hollow with a bowl-gouge.. I could push-pull, angle, shove, side-cut, abuse in many different ways the Ci1 and never get a catch -- I use my Thompson tools to feel the cuts of ribbons flying off... together they a fine set of tools.. Thompson tool allow you get in the groove and you know it is right -- therapy.
