How to remove blade on Graf skate?

[mikeweb 0]

How would one remove the blade on a Graf skate? They have the big screw on the back but even after removing it I cant seem to get the blade free.

Edit: Nevermind, I just had to loosen the screw and push the shaft down

Be careful not to overtighten it when you put the blade back. It's very easy to cross thread it and you won't be able to tighten the blade in properly if you damage it. Just snug it up and don't crank it too tight.
