I've been cutting Stencils on just about everything I own. My pots and pans are etched and cups and mirrors, right now I'm doing a steel tray but it doesn't work as well as stainless steel. The blade won't glide across the metal at all it actually feels like the steel is sucking my blade in and making it really hard to cut the contract paper and my blade gets super dull as soon as I start. It's just like the aluminum cake pan I did. I was thinking about trying the curved blade maybe then the metal would've grab it as bad. All advice welcome!
