sword blanks from leaf springs

[Howard Clark]

In general, springs are made from steels that are quite suitable for making blades. Almost any spring will make a decent blade if heat treated appropriately. As springs, they are a bit soft for supreme edge holding, though they are "hard enough" to make a halfway decent knife without changing the hardness by heat treating.

Beating a cold spring flat, from it's arched condition is very difficult, and silly, and not good for the steel's microstructural condition.

Would an old sharpening steel be worth recycling? I'm looking at a Henckel steel, at least 20 years old, which has lost its --- whatever makes it hone, I suppose the surface pattern has worn down over the years.
