I have about 7 but my favorite is a magnetic bowl or tray that I bought at an auto parts store. It is about 7 inches in diameter and magnetic. Mechanincs use it to hold nuts and bolts when they are working on cars. I love it!! Only about $6.00. This one sits on my cutting table. The rest are scattered all over the room, some bought, some made, some magnetic, some soft. They are everywhere here.
