Have people chewed out boneless chicken feet?

That's not true. It was scraped with a knife.

Bone removal of chicken feet requires four steps:

1. Wash the chicken feet, and cut the back of the feet of the chicken feet along the joints with a knife to shorten the joints. Be careful not to break the meat and tendons.

2. Pull up all the chicken feet by hand, cut the parallel leather surface on the leg bone with a knife, and tear the inside of the meat and bone by hand.

3. The knife edge cuts the bone along the leather surface, so that the chicken leg bone can be completely removed.

4. Place the knife edge parallel to the inside of the chicken feet, cut along the bones, and remove the phalanges of the feet. Be careful that the bones taken out should not be fleshy and sinewy. It's done.
