Nuclear Nutcracker

Tough nut to crack? Not with the Nuclear Nutcracker.

Special gearing and long handle give tremendous leverage for cracking any nut, from fat hickory nuts to notoriously tough black walnuts to tiny chestnuts.

Unlike with other crackers, you cannot completely crush the meat by cracking the shell too much — makes cracking nuts a breeze and fun!

Hand-welded of 1/8" and 3/16" steel.

Automatically adjusts to size of nut.

Great gift for tool and gadget guys.

4"W x 11"L x 5"H.

Weighs 3-3/4 lbs.
