Thanks for the videos-I guess I have the most current cutters even though I bought it 2 yrs before that video was posted. I find it interesting how she kept saying martelli blades are the longest lasting and cheapest. My 60mm blade didn't last at all and they are not cheap. I bought other brand 45 mm blades but I guess I have to use the martelli brand 60mm so I almost never use my 60 mm cutter.
