I wrote KQED and got an off-putting arrogant unhelpful response to a cooking show I just watched with the "teaching chef" always using too long a knife!
It is less controlable and more unsafe, I think.
My mother and sisters also have this bad habit of using the same a 8-10" blade, for everything!
Jaques doesn't do it.
So I stumbled around Google search and finally found "Joanne Weir's Cooking Confidence Show" feedback on joanneweir.com...
No answer yet, but I have seen this too long a knife issue on other PBS shows.
Regret KQED was so unhelpful...
Safe and healthy cooking!!
