Wüsthof prints the steel it uses on the blades of many of its knives: X50CrMoV15[0], which is also called 1.4116 and 5Cr15MoV.

It's not in OP's tool, but this article[1] by metallurgist Larrin Thomas includes it. His ratings are 2.5 for toughness, 2.5 for wear resistance, and 8 for corrosion resistance. It is a bad steel for any kind of knife and especially bad at Wüsthof's prices.
