Nut Cracking Anvil

| View Cart ⇗ | Info

The study experimented with the processing of nuts, and the first step in the process was, of course, cracking the nuts. To do this nuts were placed, one at a time, on stone or an anvil stone and then struck with a smaller hammer stone. As nuts were cracked in this manner a pit developed in the lower stone; the pit deepened as additional nuts were cracked, and this facilitated the cracking process since nuts were held rather stationary in this seat.
