I complained at lunch the other day that we had no substitute for stainless flatware. Using our hands seemed the only healthy alternative to avoiding toxic stainless alloys leaching into the food. The solution came to me all of a sudden - chopsticks. Chopsticks come in all materials, and one of those is non-laminated wood, usually these days, bamboo. This should be an acceptable and preferable substitution. It isn't perfect, you can't eat yogurt with chopsticks or spoon matcha into a glass with them, but any improvement in environment is an improvement in health. And it really adds up.
One of the unseen things that experienced cooks do is to match their food preparation with their circumstances. So, when changing over to chopsticks food can either be in liquid form or usable by chopsticks.
