Query: Kenkel Hardshell Nutcracker works as described.

One must supply the wood for its base. It takes a few attempts to learn the correct amount of pressure to crack versus smash the nut shell. We had our first hickory nut bread last night. Delicious. It still takes a fair amount of work to recover a whole nutmeat - may be impossible but the nutcracker at least does the outer shell job for you.
