The other image after closer inspection I don’t even know what its meant to be.
Reminds me of a watchmaker’s screwdriver.
Then again, that’s exactly how I am using them. No need for a special hand. They have that nice rotating thing on top so you can hold it in place and turn it either way…
Edit: on second thought, it WOULD be nice to have a thumb or two extra to hold the base while working. However, we already invented the vise…
I think that’s the point of the second image as well - you could hold it in the air. The red tips are the “thumbs”. Not two thumbs opposed to each other, but another thumb to oppose the pinkie when the “primary” thumb opposes the index and middle finger.
It’s a death trap on US roads. It’s going to be run over by a pickup truck on the first day.
