Is this katana sharp? Can it be used for cutting?

Yes! Our katanas are extremely sharp and built for real combat use. Each sword is hand-forged using high-quality steel, ensuring the blade meets the standards for both hardness and toughness required in practical fighting swords.

I am buying this katana just as a display piece. Do you provide a display stand?

We fully understand that most people buy katanas primarily as display pieces (katanas do enhance the aesthetic of any space beautifully) rather than for actual combat use.

To support this, we provide a free wooden display stand and a cotton sword bag with your purchase. This way, you can showcase and protect your katana right away.

Can I have my name engraved on the blade?

Absolutely! You’re welcome to have your name, a personal motto, or even a custom design engraved on the blade. We offer this engraving service completely free of charge.

Simply leave a note saying “engraving” at checkout, and we’ll contact you by email within 30 minutes to confirm your engraving details and preferred style.

How soon can I receive my order?

If the katana you purchased is in stock, we can ship it on the same day. This means you may receive your katana within 7 days.

If the katana is not in stock, we will need about 3 days to hand-forge your order after receiving it. The estimated delivery time is usually between 7 to 14 days.

Why is there oil on the blade when I received the katana?

To protect the blade during shipping, we apply a light coat of professional blade oil before packaging. This prevents potential scratches or moisture damage caused by uncontrollable factors during transit. The oil is completely harmless to the blade.
You can easily clean it with warm water and a small amount of dish soap. Please make sure to dry the blade thoroughly after cleaning to prevent any risk of rust.

Can I buy this katana as a gift for a minor?

If you are purchasing a katana with a sharp blade, we do not recommend giving it to minors, as it can be very unsafe. However, we do offer an option with a blunt blade.

If you intend to buy a katana as a gift for a minor, we strongly recommend choosing the blunt blade version. This option eliminates safety risks while still allowing them to enjoy the beauty and appeal of a katana.

What if I don’t like it?

We’ll give you your money back! (Yes, even if you’ve used it for a month.)

All our products come with a 30-day 100% satisfaction money-back guarantee — if it doesn’t work for you, just send it back and we’ll refund you in full.

Free shipping?

Yep! We offer FREE U.S. shipping as well as FREE shipping worldwide.
