I can completely agree with you on the backrounding. I do use my finger as a spring, but I do believe I just need more practice. As far as the petal lifter goes I did use one. Now as far as the proper use for the tool goes I have no clue. I do know it is intended to cut into the leather under your petals, but what I am scared of I guess is the depth of puncture. How or what way should I use this tool
