Review of Magcraft NSN0656 1/2-Inch by 1-Inch Rare Earth Rod Magnets, 2-Count

I am in the commercial construction trades and purchased these magnets for myself and some co-workers. These magnets were very strong. My friend had one in his front pocket, and it held a 22 ounce Estwing hammer on the outside of his pants as he walked around. I drilled and epoxied three into a 48" wooden level, not sure if that was enough pulling force for the level. This magnetic level has more magnet strength than I expected, easily more than any magnetic level I have ever used, including those with rare earth magnets.
