Yes they are made to work with the machine. They will out last regular blades by 3x. If you are not having exact cuts see details above as to what blade type to use it is not because of a dull blade usually. These blades are harder than metal
Yes they can however if you use your machine as much as I do you might not be happy with them. I this blade only lasted about two or three weeks. I just bought some cricut blades but hash haven't used them yet so I don't know if they will last longer or not.
Good question! I can honestly say, I'm not sure. I would assume they would work as the Cricut blades, but I have not tried them as of yet. I own five of the machines, the latest is the Explore and have not used them yet. Crafting is delegated for the Fall and Winter, Spring and Summer, gardening. Not much help I'm afraid! Good luck. G.P.
