The Hidden Blade is a sleek, retractable dagger designed for stealth assassinations, featuring a sharp, single-edged blade made of high-quality steel with a subtle Damascus pattern. The blade is housed within a compact, forearm-mounted mechanism crafted from aged leather and reinforced with dark iron fittings, showcasing intricate Norse engravings. The device operates with a smooth, spring-loaded mechanism, allowing the blade to extend and retract seamlessly, with a matte finish to avoid light reflection.
