Before choosing an anime sword, consider its purpose—display, cosplay, or functional use. Authentic replicas vary in quality, materials, and craftsmanship. Look for high-carbon steel if you want durability, or lightweight stainless steel for safe cosplay. Ensure the design matches your favorite character or series, and check for licensing if authenticity matters. Blade sharpness, weight, and detailing also affect usability and appearance. Choose a trusted seller to guarantee quality and accuracy.
