Kun Wu, Taia Sword & Yunyou Fan: WANWU EDC Guide

Three WANWU pieces, three different jobs

The Kun Wu, Taia Sword and Yunyou Fan share a maker and a Chinese-inspired design language, but they are not interchangeable fidgets. The Kun Wu is a spinner ornament, the Taia Sword is a magnetic slider, and the Yunyou Fan is a multi-tool built around a folding fan. Your first decision is which motion you actually want in your hand.

Use weight and material as your second filter. The supplied records list the Kun Wu at 138g in titanium and 248g in bronze, the Taia Sword at 64g in PEI and 98g in bronze, and the Yunyou Fan at 91g in TC4 titanium. Those numbers tell you more about daily carry than any styling photo.

What the listings confirm

• Kun Wu: Kun Wu: 150 x 14mm, R188 bearing in the spinner buttons; titanium 138g, bronze 248g. The bearing defines the play as spinning rather than sliding, and the bronze version is heavy enough to notice in a pocket.

  

• Taia Sword: Taia Sword: 82mm long, 9mm thick; PEI 64g, bronze 98g; magnets hold the main body without glue. A slim slider with a magnetic build suits pocket carry and pull-and-close play.

  

• Yunyou Fan: Yunyou Fan: TC4 titanium ribs, custom paper fan surface, 91g. This is the only piece here with a paper surface, so it plays and carries differently from the all-metal options.

Match the motion to your fidget habit

Pick by the action you repeat most, not by which piece looks best on a desk.

• Kun Wu — spin: The R188 bearing sits inside the spinner buttons, so the Kun Wu rewards a rolling, repetitive motion. The titanium body is unpolished and the zirconium buttons are blackened and polished, giving a two-tone look. At 248g the bronze version is a desk or display piece more than a light pocket carry.
• Taia Sword — pull and close: The Taia Sword is a slider with a tuning fork sound when pulled out and closed, and the listing describes clear feedback during play. The 82mm length and 9mm thickness keep it slim, and the 64g PEI version is the lightest of the three.
• Yunyou Fan — open and handle: The Yunyou Fan is listed as a multi-tool with a fan surface of high-end custom paper and thickened TC4 titanium ribs. It is for handling and opening rather than spinner-style repetition, and the paper surface makes it the most care-sensitive choice.

Material choices that change the feel

Each piece offers variants that alter weight, finish and price. The catalog prices shown are USD 184.95 for the Taia Sword, USD 74.50 for the Kun Wu and USD 52.50 for the Yunyou Fan, with higher comparison prices listed alongside.

• Kun Wu: bronze versus titanium: Bronze/Cupronickel is the vintage-styled heavy option at 248g; Titanium/Zirconium is 138g with an unpolished body. The listing also offers White PC, Black PC, leather scabbards without the sword, and a stainless steel display stand without the sword — read variant names carefully so you do not order an accessory alone.
• Taia Sword: PEI versus bronze and zirconium finishes: Ultem (PEI) with stainless steel is the 64g version; Bronze+Titanium is 98g. Zirconium variants include Crystal Sealing, Blackened Zirconium and Oil Slick Zirconium with different decorative themes. The listing notes that the Zirconium edition comes with a stand.
• Yunyou Fan: one listed material: The only variant shown is TC4 Titanium at 91g, so there is no lighter or heavier alternative to weigh.

Decision rules before you order

Use these checks to narrow the field quickly.

• Choose the Kun Wu if: You want a bearing-driven spinner with a weapon-inspired ornament look and accept that the bronze version is a heavy 248g piece.
• Choose the Taia Sword if: You want a slim magnetic slider with audible feedback and a choice between a light 64g PEI build and a heavier 98g bronze build.
• Choose the Yunyou Fan if: You want a fan-format multi-tool in titanium and will treat the custom paper surface as the delicate part.

What the listings do not settle

The supplied records do not give a recommended age range, certification or safety rating for any of these three pieces, so they are not confirmed as children's toys. The Taia Sword listing mentions magnets in the main body; keep that in mind around small children and magnetic-sensitive items, but do not treat this article as a manufacturer safety instruction.

The records also do not include care steps for the Yunyou Fan's paper surface or the Kun Wu's bearing. If those details matter to you, check the full product page before buying rather than assuming a maintenance routine.
