"I built it 4 years ago when I had a couple buckets of walnuts to crack. I didn't like the regular hand-operated nutcrackers," says Clarence Vetsch, who built a big, easy-to-use foot-powered nutcracker that lets you crack nuts at high speed.
To crack, you simply step on a foot pedal which pulls down on a lever that cracks the nut against the head of a bolt. The bolt can be screwed up and down to accommodate different size nuts. The pedal is spring-operated. Vetsch, retired, makes them in his garage. He's sold about 100 of them from Ohio to California.
