I was taught to choke up on the blade by a Western chef as well.
Then I went to Japan and was told to only hold the handle for their style of knives. Apparently, they balance the weight of the blade and handle differently there.
I tried to choke up on the blade at a very professional knife store in a market and was immediately corrected by one of the Japanese chefs there.
Then, the following evening, we went to a Michelin star rated kaiseki, all of the chefs were holding the knives by only the handle, no choking.
I realized I probably looked very foreign choking up on the blade in that store earlier. Humbling moment!
There is something which grabs your attention and fills you with admiration when you see a Master displaying his expertise so effortlessly and easily.
I am now going to watch more of Mr. Jacques Pepin.
They still refuse to do the proper technique. They cut themselves regularly. Their stubbornness knows no bounds. Even when it involves literal blood at least once a week.
Once I realized my wrist should be straight when using a knife and adjusted my stance to be slightly angled away from the cutting board, my knife skills leveled up a ton.
The only cooking knives really meant to be held always by the handle entirely are heavy butcher cleavers, that have all the weight in the blade and you're meant to sling it around. Even a paring knife is often best used by holding the blade.
