I wanted to give praise to "Clean Cut Blade." I have a Roland XC-540 & have nothing but trouble with previous OEM cutting blades. I found that I just had not been getting much "life" out of them. In changing & using "Clean Cut Blades," I have never been happier with a blade before as I am now. I get much more longevity out of them & the cut is perfect. Great job Clean Cut as you have a customer for life with me now
