Yeah, I think it depends more on the kid than a set age.
There's s difference between choking hazard size (grapes, hotdogs) vs my child is unable to take e proper bite (breadsticks, pizza, sandwich).
My dd will often shovel a lot of bit size pieces into her mouth, when if I would have left the food whole, she would/could take small bites.
I do like to cut messy foods as she can't use a knife. So I cut and then she uses a fork.
It is hard to judge. Watching a friend's baby, I gave the young toddler an entire baby wafer, only later to see the mom break it into really tiny pieces. Maybe she was working on the pincer grasp, but he had no problem biting off the proper size piece.
So trial and error. When attempting a new food watch and see.
