The blades are not available yet but coming soon.
As far as the trimmer, I have it and like it but they are replaceable blades so yes, they will wear out. I am not sure if they will last longer than a fiskars or not. My problem with my fiskars was I had the wire guide and the wire has gotten warped, and it makes it look like I am cutting off. It was driving me nuts! I like the score blade and made it very easy to do a card!
