There is a lot of great advice in all the comments!
My best advice when it comes to chipping... Is practice with a variety of clubs off the fringe, in the rough, in heavy rough, in a divot, off the mulch, and find which works best for you.
My 8 iron works best for me because I can bump and run it or even hit a small flop shot with it.
But I also use my 9 or 52 degree wedge too. I use my 56 out of the sand. I have a bunch of videos on it... I even did a hands on review of the square strike wedge. Don't fall for the Commercial on TV. You already have the club in your bag. Just have to test them all out
