Ingenuity in Every Detail

• The "Magic Moment": The core feature is a revolutionary sliding mechanism that allows the two separate extended-length knives to combine into a single, compact housing. The blades are designed to unlock each other, allowing them to seamlessly slide back into their own handles.
• Secure and Sturdy: Each knife features a robust tanto design and is built to be very sturdy when separated. Invisible, integrated magnets hold the knives closed securely.
• Designed for Purpose: The stability of the knives is comparable to a well-made folding knife. They serve beautifully as a unique collector's piece and a useful normal knife
