High carbon steels (1060, W1,
tool steels, etc.) generate sparks easily.

stainless steel, 5160, etc.) are more difficult and generate fewer sparks. The steel must be hardened but softer than the flint-like material striking off the spark.
Old files, leaf and coil springs, and rusty gardening tools are often repurposed as strikers.
