Iron, the pure metal, is a deceptively difficult metal to find. The ordinary nail that you'd use on a two-by-four, and the head of the hammer you'd nail it with, are both made of "iron", yes, but both have small amounts of other elements added to improve various properties. A nail made of 99.9% pure iron such as offered in these cubes, for example, might be both more expensive (because of the added refinery steps required to get to this level or purity) and simultaneously more prone to breaking or bending all wrong when hammered. So practically nobody uses pure iron for anything. Yet, according to one industry report, a growing number of old school blacksmiths are requesting the pure stock for specialty projects like gates and artwork. Why? Because it turns out that purified iron resists rusting better than ordinary grades of steel. Now how's that for irony?
You wouldn't want to test this improved resistance to rust with this here expensive toy. Resistance does not equal foolproof. But on the other hand you can at least expect it to hold up better than, say, a bunch of nails from Home Depot!
