What you get

Three parts. One katana.

The handle, a four-section telescoping blade that nests inside it, and a cap that covers the handle opening and locks the blade in. Show it fully extended, or keep it fully collapsed.

Two Fukutsu katanas on dark slate: one fully extended with its curved four-section blade, one fully collapsed and standing on its guard

Fully extended or fully collapsed

Two ways to show it. The blade sits either all the way out or all the way inside the handle.

Close view of the black handle: raised diagonal wrap over a scale-textured grip, with the round guard at the base of the blade

Wrapped handle & guard

Raised diagonal wrap over a scale-textured grip, with a round open-work tsuba.

The collapsed Fukutsu standing upright on its round guard, with the whole blade nested inside the wrapped handle

Collapsed

All four blade sections nest inside the handle, and the cap closes it up.

All photos show a printed Fukutsu in black PETG. Backgrounds are added.

How it works

Nested in. Extended out.

Fukutsu has three parts: the handle, a four-section telescoping blade, and a cap. The blade lives inside the handle until you want it out.

Left: the collapsed Fukutsu standing on its guard. An arrow points right to the same katana fully extended.

Collapsed

All four blade sections nest inside the handle. The cap covers the handle opening and locks the blade in.

Extended

The four sections slide out to the blade’s full length, ready for your desk, a shelf, or a cosplay.

Back in the handle

Slide the blade all the way back into the handle and close it with the cap to store it or carry it in your con bag.

The idea

不屈 — “unyielding.”

Fukutsu started as a simple challenge: fit a whole katana on a small printer’s bed. The answer was to fold the blade into itself. The name means an unbreakable spirit — the kind it takes to reprint a design until it works.

FAQ

Questions, answered.

How do I order?
Send a DM with the word “KATANA” to @fukutsu.prints on Instagram. Tell us the quantity, color, your full name, and your US shipping address. We’ll reply with your total and payment details.
How do I pay?
Venmo Goods & Services, which includes buyer purchase protection, or Zelle. Payment details are sent by DM after we confirm your order. We will never ask you to pay as “Friends & Family.”
How long does it take to arrive?
Each katana is printed to order, so it ships in 3–5 business days. USPS Ground Advantage then takes about 2–5 days. We DM you the tracking number.
Do you ship internationally?
US only for now. DM us and we’ll let you know when international shipping opens.
Is it sharp? Is it safe?
No. It’s a blunt PETG plastic desk toy and cosplay prop with no edge and a rounded tip. It’s meant for adults and collectors and is not a toy for children under 12. Please don’t swing it at people, pets, or faces.
Can I bring it to a convention?
It’s a plastic prop, but every convention sets its own prop and weapon rules. Check your event’s policy before you bring it.
Can I get a custom color?
All black is our standard. DM us the color you’d like and we’ll tell you if it’s in stock. Custom colors may add a small charge.
What if it arrives damaged?
Send us a photo by DM within 7 days of delivery and we’ll reprint it or refund you. See Shipping & Returns.
