I thought it was my blade but have found out also that my cutting mat is gouged up. I used my cutter on a self-healing mat and boy what a difference. When I can afford it I'm getting a new mat for my cutting table. Found a company that will cut to fit with and without marking. Think someone on this list gave us the website too. I need a 4 x 7' cutting mat so that's the reason why I need to wait. Plus they will send the cutoff section to you so you can make them into ones you can put next to your sewing machine. Works for me............:-D
