Single-Blade Pocket Knife with Jigged Bone Handle

This is a small, single-blade folding pocket knife, likely of a 'jackknife' or 'penknife' style. The handle appears to be crafted from jigged bone, characterized by its reddish-brown color with lighter streaks and a textured, carved surface designed to improve grip and aesthetic appeal. The bolsters, visible at both ends of the handle scales, are made of a brightly polished metal, possibly nickel silver or steel, showing some reflective quality. The single blade is a spear point or clip point design, made of what appears to be carbon steel or stainless steel, exhibiting a slightly dull finish, consistent with some use or minor tarnishing. There are no clear manufacturer's marks or signatures visible from the provided image, but such marks are typically located at the base of the blade near the pivot. The overall condition suggests a vintage item, with some expected wear and patina on the blade and possibly minor scratching or dullness on the bolsters. The construction appears robust, featuring riveted handle scales that securely attach the bone material to the liner. This type of knife was commonly produced throughout the 20th century, and without specific marks, it's difficult to pinpoint an exact age, though the materials suggest a period before the widespread use of synthetic handle materials. The craftsmanship appears to be of good utility quality, typical for a functional everyday carry knife.
