[b-hebrew] Iron sharpeneth iron? (Prov. 27:17)

Even magnetism is not a good answer. Good permenant magnets were largely unknown before about the 1930s, and even compas needles needed to be constantly renewed (using a lodestone) at the time of Columbus and other early European explorers as the metal could not maintain its magnetism. Any metal worked by blacksmithing will have no magnetism. (Most modern permenant magnets are more properly metalic ceramics, or non-metalic ceramics or plastics with metals mixed into them, than regular metals.)

Sharpening, on the other hand, can have steel sharpening steel. The reason for it is differences in tempering. Cutting edges, such as axes and knives, hard temporing is not desirable, as hard steel is also brittle. Particularly axes, if they are brittle, will break when used to cut down a tree. Knives used in cooking will also run into the same problem to a lesser degree. The softer tempering does not hold an edge as well as a hard tempered steel. However, chisels used in stone work and files can be tempored very hard: the stone chisel because it can be made fat to counteract for its brittleness, and a file because it is not used in impact situations. While a woodsman’s preferred tool for sharpening his ax is a special stone, when he wants to travel lightly, he will often bring a file (steel) instead for sharpening. Similarly, I expect you have seen in cooking where the chef swipes his knife along a rod of steel? That too is sharpening. While it is not as effective as using a stone, the steel does not dirty up the knife so that the knife can be used immediately after sharpening, and if the swiping is done often throughout the day, a satisfactory edge can be maintained. Steel sharpening steel.

But even “soft” tempering of steel results in a harder, sharper edge than bronze, which is why tempered steel is the reason for the “iron age”. Iron that is not steeled is a very inferior material for almost all uses.

Now the question is, how does a man sharpen the face of his neighbor? I understand it that in personal interaction, a person, as his neighbor bounces ideas off of him, can point out weaknesses in an argument, challenge assumptions and all in all sharpen his neighbor’s outlook. This is not physical, but spiritual and mental.
