Nuts are always a tough nut to crack. Either you smash it too little or too hard and they shatter. This genius solution will help you – it’s basically a conical spring containing a firmly fixed pin. The nut is put in the stainless steel bowl provided and the spring placed above it. Hold the spring with two fingers, pull it up and release it and the pin will slam down and crack the nut. Simple and utterly effective, isn’t it?
