This is a Spyderco replica. I believe it's a Para 2 or similar. Please check the overall length and blade length in the photos. Blade thickness is approximately 3mm as measured. The blade material is stainless steel, but details are unknown. The blade is centered, and there is no blade play. The construction of each part is solid. The blade opening and closing is stiff, especially when closing, and it doesn't snap shut easily. Only paper cutting test performed; it cuts well. The box is included, but it is damaged. Please note that I only own a Spyderco Police, so I cannot answer any questions about other models. Please refrain from purchasing if you are concerned about minor details. No returns or exchanges, please. Folding knife Outdoor Benchmade Cold Steel Microtech Kershaw
