Is there a special tool available just for cracking open pistachio nuts? I'm asking because as I have gotten older, I have developed severe arthritis and joint pains, making opening them with my fingers very painful. I've always loved pistachios and hate having to ask my wife to crack them open for me.
I have tried using regular nut crackers, but the pistachio either slips out without cracking or the nut inside gets crushed.
