To protect your valuable knife and ensure the safety of delivery personnel, please make sure to follow the “Knife Packaging Instructions” below and pack your knife securely before sending it.
Knife Packaging Instructions
Step 1
Place the knife on newspaper or other similar paper, and wrap the blade tightly with no gaps. Using multiple layers of paper will increase strength and provide added protection.
Secure the entire package with tape for extra safety.
Step 2
Sandwich the knife between pieces of cardboard.
Make sure to cover the entire blade securely, leaving about 2–3 cm of space beyond the tip.
If the extra space is not provided, the tip of the blade may pierce through the packaging during handling or transit.
Step 3
Secure the cardboard with tape.
Make sure to firmly tape around the cardboard as shown in the image to prevent your knife from coming loose.
After packing is complete, gently pull or move the handle to ensure that the knife remains in place.
