The Case Peanut is a part of the Yellow Synthetic Family. The distinctive yellow handle brightens this family while maintaining its toughness. Peanut knives get their name due to their small petite size fitting discretely and conveniently in a pocket. This durable folding knife two full length blades the Clip blade and the pen blade. The Clip blade is commonly used as a multipurpose blade and preferred for detail work while the Pen blade is great for light work. This knife is made with our Chrome Vanadium CV steel and a smooth yellow synthetic handle. Case Chrome Vanadium blades are known for their edgeholding ability and easy resharpening. However they are less resistant to rusting pitting and discoloration than stainless steel. We recommend keeping a thin film of oil on the blade to maintain the finish. Made in Bradford PA. USA from domestic and imported materials.
