The problem is that the metal is very prone to rusting, so I have
to oil it after every cleaning, and temper it like a cast iron

will use it on the stove), it has held up pretty well. It ain't
pretty by any means, but useful.

How are you "cleaning" it? Wiping it out with a paper towel should be
sufficient. Do not ever subject an iron utensil (or maybe your skillet) to
water.

Don't wash wooden salad bowls either.
