When collecting Ekco Flint kitchen utensils, you will come across these two versions of the 5" square handle strainers... one version has the stainless metal support bands - the other does not.
I have used both and find each works well... for average home kitchen use, the bands are not necessary.... and it is much easier to keep the mesh clean. If doing heavy canning or constant food prep, the bands would have an advantage, since they help support the mesh form under a load.
We use the bandless 5" version for washing our rice (2 people serving). It works very well for the task... wash immediately after using to keep the mesh clean.
Ekco made a smaller 3" diameter version as well...
