And by it, I mean anything!  If you are using the Maker 3, first off, I am sorry and I understand, as I got roped into getting on myself.  Second, this knife simply shreds everything, basswood, matboard, cardboard, I mean ANYTHING you put into it.  Cricut brand stuff, other companies stuff, all of it!  I am starting to think that the Maker 3 is a lemon.  That said, I wouldn't buy the Maker 3 OR the Knife Blade, unless you are looking to runa block of cheddar cheese through it.

Don't even get me started on trying to tranfer they're new \"Smart Vinyl\" from the backing to the transfer tape ..... let's just say .... it's easier to cut out the letters with a scissor and scoth tape them to your project.  Kinda like the unibomber would do.

Thanks for killing my business Cricut.  Time to get my old Explorer Air 2 out of storage.  Or maybe look at the Sillouette??
