Start with a sharp knife.
A dull blade asks you to push harder. A sharp one lets you stay in control. Keep it maintained, give it your full attention, and never try to catch a falling knife.
Knife Skills
The goal is not to look fast. The goal is for the knife to go where you intend, every time. Slow, repeatable movement is the beginning of both confidence and speed.
The short version
“Speed is what happens after good movement becomes familiar.”
What helped me
A dull blade asks you to push harder. A sharp one lets you stay in control. Keep it maintained, give it your full attention, and never try to catch a falling knife.
Put a damp towel beneath the cutting board. This takes seconds and removes the wobble before you make the first cut.
Curl your fingertips back and let your knuckles show the blade where to go. Find a calm rhythm. There is no prize for rushing.
If you want to try it
This is practice that also gets dinner started. Use an onion, a stalk of celery, or whatever you were already planning to cook.
Set the board on a damp towel and clear enough room for the knife, the food, and the finished pieces.
Use a comfortable grip, curl the fingertips of your guiding hand, and make the first few cuts slower than feels necessary.
Look at the pieces. Aim for consistency rather than a perfect shape; even pieces tend to cook at the same rate.
