AH the Martelli - i love to use it. However it seems to hate me when I have to change the blade - sigh. I use angled Olfa and have for years. I use the angled 45 and 60 for straight cutting, the 28 for curves and the 18 for ripping out long oopsies (If it's only a stitch or two I usse a seam ripper bit the little rotary blade is easier on my hands). I think I will try the Famore although I prefer the angled cutters with my hands.
