Abstract: A nut cracking device with a frame having elongated, parallel members that surround a mechanical advantage device, such as a hydraulic jack. Top and bottom channel members are mounted at opposite ends of the frame members to separate the frame members and form a rigid frame structure. An anvil with texture to reduce slipping and increase pressure is mounted to the top member and extends toward the jack, on which a table is mounted. A nut may be placed on the table. Upon displacement of the jack's shaft, the table moves toward the anvil and any nut on the table is clamped, and ultimately fractured, between the table and the anvil. A hand-grippable knob permits manual bypass of a valve to permit the table to be pulled away from the anvil by springs mounted to the table.
