MZ SKEETER 4,708 Posted January 7, 2011 when they get dull. It all depends on what you are cutting. reflective vinyl can dull blades faster and so can chrome and other metals. I use blades for months and I cut everyday. Then I give it a bit more force and use them a while longer, Get all you can out of them, As long as the cuts are still good. If you are getting alot of problems, with choppy cuts,or not cutting the vinyl good,or if the blade tip is damaged... change it. Share this post Link to post Share on other sites
