Yes indeed, A good kitchen knive which should be sharpened by a special grindstone, is the only thing an experienced cook needs.
We have no such blender in our household, only an old Moulinex hand blender. (stick)
This is 30 years old.
I got a new one as a present from a newspaper.
I worked only ONCE!!! and then there was a shortcut and a bad smell.
When I opened it, I found a real tiny little motor inside and the "control board" was burned. This is technique of today.
(obsolescence of course)
Have a nice "labour day"!
