I've done the same thing with my Lazer. Take it to an automotive shop and ask them if they will take it off for you. Unless you've got a snap-on, matco, or other professional gun you won't get it off. They might even have a 3/4" gun that will take it off very easy. If you try and wedge the blade and use a breaker bar you will probably bend the blade- $15 bucks down the drain. The shop might charge $5 bucks to zip it off. Money and time well spent if you ask me.
You don't stop playing because you get old, you get old because you stop playing.
