A: No, this is not for the Auto-Blade housing. This specialty blade is sharper and stronger than the blades that come with the Cameo and we use the cb09 Graphtec Blade holder (also on our website), which then fits into the grey plastic housing that came with your Cameo. The Auto Blade can be finnicky at times and we've found we get much cleaner cuts with this TRW Clean Cut blade.
Remember, you will need to purchase the Graphtec blade holder to use this blade in your Cameo. We go over the blade and how to click the Graptec blade holder into your Cameo in this quick tutorial (please copy and paste to a new browser window): https://youtu.be/_Jdyvz0dT0U
