I've never used the Fiskars cutter and only used an Olfa when I didn't have mine handy. I use a curved handle Quilters Rule cutter or one of the old brown Dritz cutters (mine are both 20 years or older!). I did try Fiskars blades and found that they really dull quickly, so I only use Olfa blades which last a long time and can be sharpened well. I would like to have a 60mm cutter, tho.
