I haven't tried anything like that. I tend to use the B plate as the one that gets the cuts in it and just move it around, so I am cutting near the top, middle bottom, sides, etc. I also flip it and use both sides. When it is bad and won't cut well anymore, I use a coupon at Michael's or one of the other stores and get a new set of B plates cheap. I'll have to try Ellie's idea with the hot water and bending it opposite. May try the oven idea, too.
