Non-Magnetic Copper Beryllium Wrenchs and Tools
You might be looking at this image and saying, "Good luck getting those off!" Not so.
I am using non magnetic wrenches designed for use around powerful magnets like MRIs. They are made from Copper Beryllium alloy. You don't want your wrench flying out of your hand, or scratching the coating off of the magnets. These are a must around serious magnetic fields.
