Sharp out of the box and stays that way for decades.
Why Not Just Buy the Cheap One?
A $20 “stainless” knife from Amazon Basics is stamped soft steel that dulls after one meal. Wusthof uses precision-forged high-carbon steel with a 58 Rockwell hardness. It holds an edge, won't chip, and resists rust when cared for.
The Buy-Once Math
Replace that cheap knife every two years? $60 total, plus hours fighting blunt edges. One Wusthof costs more but lasts your lifetime if you store it right. Buy once, never curse your onion again.
