If you're not looking for straight cuts, this blade stack is for you. This blade deflects so much that it loses air almost as well as a parent does when a five-year-old asks where the child is from. If this blade were a human then it would definitely be a politician due to its outstanding ability to deflect rather than strike directly. Not to mention, this little fella immediately deflated like he's going to be a crowbar when he grows up. When I mean fast I mean within 2 hours of use. Only buy this blade if you want to cut circles.
