#cricutreplacementblades

Was looking at the replacement blades for the cricut,and looking at the blade it came with, and it was like, how does this even work? Do I need to buy housing for the blade? The housing is at least $20 and just the replacement blades with no housing were only $7 on sale. So google. Thanks to that, I found out...the button on the top? If you hit it, the blade can come out. And to put it back in, it just magnetizes back! Just be careful because sharp blade.
