Yes, worry about the knives! The urchins are replaceable!Nah. They'd mess it up. I get a bit obsessive about the order I do stuff in, so it's easier to not have to worry about ordering a squad of urchins around in said correct order. Plus, they'd ruin my knives!
If, however, I decided to do a large batch of meaties, I would absolutely draft them into service, and risk the damage to said knives. They'd complain, but tough luck.![]()

I'd set them all to plucking. The knife work is the easy part.
