The image shows an old, rusted knife with a long, curved blade. The blade appears to be made of metal and has a rough, textured surface. The handle is made of a dark, weathered material, possibly leather or metal, and is attached to the blade with a metal sheath. The sheath is also made of the same material as the blade and is secured with a small metal buckle. The overall appearance of the knife is weathered and aged, suggesting that it has been used for a long time.
