This is a vintage metal buttonhook, an accessory tool most commonly used in the late 19th and early 20th centuries to help fasten buttons on boots, gloves, or clothing. Crafted from sturdy metal, it features a simple looped handle and a curved hook tip for catching buttonholes and pulling buttons through with ease. Buttonhooks were everyday essentials during the Victorian and Edwardian eras, especially for high-button boots and tightly fitting apparel. Today, they are sought-after collectibles and conversation starters, perfect for historic fashion displays or curiosities collections.
