Like already said, if used on a somewhat regular basis, not hard. Try eating peanuts, it's not as hard as you'd think. When I'm in China, I swear they cut the food in the most difficult shapes to to see me drop it!. Try a oil covered triangle shape pc veggy.
Eating Asian style is more than chopsticks. It amazing what they can do with their mouth. They can stuff a pc of bony fish in, and seconds later be spitting out the bones. Same with shrimp, gos in whole, out goes the shell.
I was a guest at a special dinner a few years back. They brought out baby octopuses, one to a small plate and each person got one. I being the guest was invited to "go first". I should inject at this time it was a bit more than a "bite". So, I picked the critter up and took a bite, spaying purple ink all across the white table cloth! Maybe they saw it coming, I sure didn't.
