Our swords and arms are by all definitions, functional. Every sword is constructed with using high carbon steel that is shaped and heat treated for strength and flexibility. Each blade uses a full tang ensure the greatest durability. We cannot speak to how our swords might be used by an individual once they have purchased an OlliN sword nor can we speak to their knowledge and skill level of sword play. This is why our site disclaimer is written as each piece is intended for display. This should not detract from the ability to use the swords as they were originally meant to be used. Each piece is carefully designed and assembled to ensure a quality sword that is durable and will last a long time, from point to pommel.
