Is Misen or Wüsthof better?
The Wüsthof Classic is better: forged in Solingen from X50CrMoV15 at 58 HRC, with superb balance, refined fit and finish, and 200 years of pedigree. The Misen is a compelling value knife, AUS-8 steel, thinner than traditional German, and a step up from your current drawer knife, but the Wüsthof is the better object. How much better depends on whether the price difference (~$60-100) matters to you.
What is Misen's steel?
AUS-8 stainless, hardened to about 58-59 HRC. It's decent steel, a step above grocery-store knives, but it's a Japanese-style steel in a DTC hybrid design, not a traditional German formula. It's thinner than the Wüsthof, which gives it a slightly different feel, and it chips more easily than a Wüsthof if you're rough with it.
Is Misen a good knife?
Yes, for the price. It's a genuine step up from cheap block-set knives, takes a decent edge, and is reasonably easy to sharpen. Where it falls short of the Wüsthof is fit and finish, long-term durability, and the overall feel of a made-in-Solingen forged blade. A solid choice if you want to spend less than $100 on a real knife.
What steel does Wüsthof use?
X50CrMoV15 high-carbon stainless, precision-forged in Solingen, Germany, and hardened with their PEtec process to 58 HRC. It's one of the most refined implementations of the standard German formula, tough, corrosion-resistant, holds a good edge, and very serviceable to sharpen.
Which is harder to chip?
The Wüsthof. Its German-style steel and geometry are designed for durability, it's more tolerant of bones, hard boards, and prying. The Misen's thinner blade is more chip-prone if you're rough with it. Neither is as delicate as a hard Japanese knife, but the Wüsthof is the tougher of the two.
Which is easier to sharpen?
Both are easy, neither requires specialized Japanese technique or fear about heat. The Misen's AUS-8 is very forgiving; the Wüsthof's X50CrMoV15 sharpens predictably. Neither poses a real challenge for a sharpener or a careful home user on a whetstone.
