The magnet in the tip of one of the grips is not really strong, but strong enough to pick up very small things. My husband tried picking up a pair of pliers, just to see if it would and it wasn’t strong enough for that. The grip is good and the grabbers worked perfectly for taking down and putting up merchandise in a very small booth at our last show. The grabbing portion would support about 2-3 pounds at least, and probably up to 4 or 5, maybe more. I wouldn’t push it too much past that.
