Crab Drawing

I bought some crab (cheap) to make lump crab cakes and crab balls. The draw back with crab, it has tiny fragments of shells in it and I do not want to cook with them in it.

Is there a special way to separate the two?

Sorry, there are really only two things you can do, you can buy a better quality meat crab, or separate by hand with great attention.

Yes, very techical, use your fingers
