Axes and Cold steel weapons

[jwallstone]

The type of damage only indicates physical, poison, etc I think.

I was going to ask the same question, since it can make a big difference in the usefulness of the item. My impression was that anyone with a sword or metal weapon would benefit. But an actual list would be great. For example, does this benefit Miner's, with pickaxes? (Not that you would want them) What about Demons, who seem to carry axes? What about Horsemen, who have a lance? It would help a lot if a little more clarity was provided by the game.
