Can't you get frozen clams? I don't know because when I was stationed in Fort Knox, I probably couldn't get clams either. And I can't live long without eating clams.
Corey, if you already froze the clams they are not that easy to open. You will have to take a strong knife, put it in the slit, sit it on a workbench and hit it with a hammer. You will probably break the shell but it doesn't matter. Frozen clam meat is like almost hard glue, it still moves but not real easy. You need to cut the muscle on each side of the slell then pry it open. Don't just hit the clam with a hammer because you will smash the shell into small pieces and it will be hard to get the meat out. The next time you get them. Semi open them while they are alive and put something in there to keep them a little open. Then it is easier to get a knife in there to cut the muscle.
