I always do the seed cracking between the nail of my index finger and the nail of my thumb. between my teeth I always end up biting too far and demolishing the inside of the seed.
I try to determine where it will crack first, then put that side outward. with most seeds it works best when first soaked in water for a while, but sometimes with seeds with thin coats (like not fully matured seeds) I find it works better to crack before soaking, since after soaking the coat will go too soft and just give in/dent when you push instead of cracking.
