How to Use the Metal Walnut Nut Cracker

• Hold the nutcracker with one hand.
• Open the handles wide enough to place a walnut between the jaws.

Step 3: Insert the Walnut

• Ensure it is centered for an even crack.

Step 4: Crack the Walnut

• Firmly squeeze the handles together.
• Apply steady pressure until you hear the shell crack.
• Be cautious not to apply too much force to avoid crushing the nut inside.

Step 5: Extract the Nut

• Release the handles and remove the cracked shell.
• Carefully extract the walnut from the shell.
• Inspect for any shell fragments before consumption.

Step 6: Repeat as Needed

• Repeat the process for additional walnuts.
• Store the cracked walnuts in an airtight container for freshness.
