What's in the Box

2 × Katana swords (20" blade, 8" grip each)
2 × Sai daggers (6" blade, 4" grip each)
Cross-back harness with weapon slots and adjustable straps

This Adult Deadpool Weapons Set brings the "Merc with a Mouth" arsenal to life, with two katanas and two sai daggers held in a cross-shaped backpack harness — the signature loadout from Marvel's Deadpool comics and films. Styled after the character's iconic weapon cache, it's the finishing touch that transforms a red-and-black suit into a convention-ready cosplay.

The katanas feature ribbed-grip handles with end caps, painted to match the comic-accurate aesthetic. Sai daggers have the traditional three-pronged design with center blade and side guards. The backpack harness uses webbing straps with adjustment hardware — fits snugly across your shoulders with katanas crossing over your back and sais slotted at the sides.

Perfect For

Comic Conventions & Cosplay Events: A must-have for Deadpool cosplayers — pairs with red-and-black suit, mask, and tactical belt for full comic-accuracy at Comic-Con, Supanova, PAX, or anime conventions.

Halloween & Superhero Parties: The four-weapon set gives you instant anti-hero cred at Halloween parties, costume pub crawls, or Marvel-themed events — wear the harness over any Deadpool costume for maximum impact.

Book Week & Graphic Novel Dress-Up: Deadpool is a Marvel Comics character, so this accessory works for Book Week events focused on graphic novels, comic books, or superhero literature — pair with your Deadpool costume for school staff dress-up days.

How to Wear It

Slip the harness over your shoulders like a backpack — adjust the webbing straps to fit your torso. Slide the katanas into the cross-back slots so they rest over your shoulders, then slot the sais into the side pockets. Wear over your Deadpool costume (red-and-black suit, mask, and tactical gear). Check convention weapon policies before packing — some venues restrict hard-plastic blades.

Cosplayer FAQs

Q: Are these katanas and sais sharp or safe for conventions?

A: They're molded plastic with blunt edges — not sharp metal. Most conventions allow plastic costume weapons, but always check the venue's specific weapon policy before attending. Some events require orange-tipped or foam-only props.

Q: Will the harness fit over my costume?

A: Yes — the adjustable webbing straps fit most adult torso sizes and go over your Deadpool suit. The cross-back design sits flat against your spine, so it won't bulk up under a cape or tactical vest.

Q: Can I wear this for a full day at a convention?

A: The harness distributes weight evenly across your shoulders, and the plastic weapons are lightweight. You can wear it for hours without discomfort. If you're sitting for panels, you may want to slip it off and carry the weapons separately.

Q: Is this suitable for outdoor cosplay photoshoots?

A: Absolutely. The painted detailing on the katanas and sais holds up well in outdoor light, and the webbing straps are durable. Just avoid rough surfaces that could scratch the plastic blades.

Care: Wipe plastic blades with a damp cloth after use. Store harness flat to prevent strap kinks.
