This cutter is improved and has two inter-changeable guides; one for straight lines and one for curved slash cutting.  You can enjoy slash quilts of Faux Chenille with curved or straight lines.  Just insert the guide between two stitching lines above the bottom fabric and push.  There is no need to use any cutting mat.  Two types of guides are included to fit the space between the seams for narrow or wide channels.  Uses Clover replacement blades #NT226 as other brands do not fit this cutter.
