We have done extensive testing on our materials with various cutting machines and have not found that the foil materials cause the blades to dull at a faster rate than other materials. I've included a link below to our article with recommended cut settings for your review. If you have any other questions or concerns, please feel free to reach out to Customer Support at 888-575-2235. https://www.onlinelabels.com/articles/sticker-paper-cut-settings
