👉 A sheet weapon, also known as a folding knife or a parry knife, is a compact, lightweight blade typically made from materials like stainless steel, carbon steel, or titanium, designed for close-quarters combat and self-defense. These weapons are characterized by their ability to fold flat when not in use, allowing them to be easily carried and stored. Sheet weapons often feature a single-edged blade, which is effective for thrusting and slashing attacks. They are commonly used in various martial arts disciplines, such as karate, taekwondo, and judo, and are prized for their agility and versatility in close combat scenarios.
