Thank you for viewing. Excerpt from the following manufacturer: "MARVEL" The pattern on the handle, applied by craftsmen one by one by hand, achieves a grip that feels like human skin. The material uses the newly developed SG-10, and the sharpness produced from ultra-hard steel is a finish that can be said to be the best in the world. [Size] 6.0 inches [Teeth] 20 teeth [Material] SG-10 (Ultra-hard and resilient material that achieves an extremely light cutting edge) [Handle] MARVEL exclusive glasses type (for both left and right hands) [Hit Point] Metal [Cutting Rate] 20-25% Since this is a used item, please refrain from purchasing if you are looking for perfection. I have had it regularly maintained, but I have never had it sharpened since I purchased it. I think it might be a good idea to have it sharpened once. Please check if the free sharpening ticket can be used.
