In one of Homaro Cantu's autobiographical pieces on Facebook, he talks about watching Matthias Merges break down fish at Charlie Trotter's, which he basically likens to a religious experience. Now the preacher gets the pulpit himself, in a Sun-Times piece in which Merges, now owner of Yusho, explains what he learns from his knives as he works:
As a chef in a high-pressure kitchen where precision is necessary, you can train your ear to hear the knife cutting through a product. I can hear a dull knife crushing through chives rather than silently slicing through each green bundle.
It's a fascinating piece and includes a video and photo gallery on proper knife care. [Sun-Times]
