yes, the circle cutter is just like an olfa circle cutter and cuts fabric just fine; all of my xacto knife's cut fabric, plastic, paper, batting, what ever i decide i need to cut. my favorite has a knife handle a little bit thicker than an ink pen and about the same length (about 7" long)that you put what ever blade you need into. i bought it in a plastic (box) kit that came with 12 different blades...the blades change kind of like drill bits... they are different sizes and shapes for different cutting requirements. i bought it at Ben Franklin Crafts about 15 years ago. i have picked up some different blades at Joannes, but have not looked to see if they have the xacto craft knife set; mainly because i already have it so i have not looked for another one. the blades are razor sharp and i have only had to replace 2 blades in 15 years.
