has anyone ever pinched the fingers ? i bought some of these neodynium
"warning extra strong" magnets from hardware store and skeptical i tried to
pinch my fingers and have had no luck, well if that is the label to give
such actions



Yes I've gotten nasty blood blisters on several occasions. Take apart
any 3.5" hard drive and pull the magnets out, they'll stick to each
other very strongly. If you can find an old 5.25" SCSI drive you'll
likely find even bigger magnets.
