I notice that much of this is marketed at "older folks". Hence the question, what is it about aging hand that lends itself to favoring larger diameter handles?
I'm not keen on adding "nooks and crannies" in which foodstuffs can hide. I tend to be obsessive about keeping things that touch food really clean! There'd be no practical way of removing the sleeve for cleaning; then reattaching for next use.
E.g., one of the rubber/silicone (no one seems to make rubber utensils anymore!) spatulas (spatulae??) that I frequently use gets disassembled at each wash -- to ensure nothing is hiding up under the blade.
The *wooden* spoon is already pushing the limits of cleanliness as it provides places for "stuff to grow". But, it can be nuked to kill off that stuff.
The discomfort subsides quickly -- ceasing motion with the spoon gives almost instant relief (e.g., taking a 15 second pause makes a big difference -- but, you can't pause while baking as the chemistry keeps running!)
