Metal used in kitchen knives (5)

I believe the answer is:

steel

(Other definitions for steel that I've seen before include "Mixture of carbon and iron" , "Hard iron alloy" , "Hard, strong, grey alloy" , "Structural metal alloy" , "Make hard and unfeeling" .)

I've seen this clue in the USA Today.
