I have a stinless steel martini shaker that I have not been able to open for a week now.... I made a matini for myseld one night, than walk away with my drink and left the shaker on the kitchen counter. Next morning, I went back to clean it up, and have not been able to open it since. So far I've tried soaking in cold water, hot water, freeze it than run under hot water, 2 grown men's hands. NOTHING WORKED! Can anyone help?
