I have a deck of Bicycle Shadow masters that handle beautifully when it come to cardistry, as it turns out they handle to well, they spring smoothly and look really cool when i do it with them, unfortunately they now have a bend in them that is affecting other flourishes, Does any know how to fix this? is from the two empty corners outwards (as in towards the back of the card). I've tried spring in the other direction but it dose not work.
