Willie,
That type of hold down is meant to be used in a vise. The edge along the thick side has a bit of taper to it and forces the opposite edge down when clamped against a part. They work well, but take a lot of room in the vise, so their use is somewhat limited.
There is also a type meant for surface grinding that has a bunch of fingers along one edge. These are pushed against the edge of a part on a magnetic chuck and flex when the magnet comes on, forcing the part down. I've used them before for grinding aluminum parts, but they are very scary.
