Edge of Duality Replica – 21cm Die-Cast Metal Sword | The Twin Blade

Solid die-cast zinc alloy, 21cm (8.3"), 54g (1.9 oz) — that's the Edge of Duality replica, shipped free worldwide by BlacksmithSONG. It was built to be swung two-handed by warriors more used to a single edge, and there's something fitting about that: a compromise weapon that ended up becoming a favorite in its own right.

What Is the Edge of Duality?

The Edge of Duality is a double-handed blade from a beloved open-world fantasy saga, originally forged using an ancient order's own craftsmanship for royal knights who'd never quite taken to that order's traditional single-edged swords. A blue-and-gold hilt, a black crossguard, and a watchful eye motif etched into both mark it as built for warriors who fight with both hands free.

A Torii Gate at the Edge of the Grove

We shot this one at the foot of a weathered wooden torii, stone steps climbing toward it and a bamboo grove rising dark behind. Paper prayer strips hang from a line strung across the frame, a pair of stone lanterns stand watch on either side, and a woven basket nearby holds a small harvest of miniature pumpkins and carrots — the kind any adventurer in this world would grab without a second thought. The blade rests against the rock at the base of the gate like it's been left there overnight. Every photo on this page is an honest shot of the real product inside that handcrafted set — no CGI, no digital backgrounds standing in for the real thing.

What You're Holding

21cm in the Real World

Roughly the length of a pair of chopsticks laid end to end — a mid-sized blade, longer than our compact pieces but nowhere near our full greatswords. At 54g (1.9 oz) it's genuinely light for something described as a two-handed weapon in its source game; the real-world version trades that heft for a slim, balanced profile instead. The in-hand photo shows exactly how it sits across your palm.

Cast, Not Cut

Each piece is die-cast in zinc alloy as a single body, then hand-finished. The geometric patterning running down the hilt and the eye-shaped ornament set into the guard are both shaped straight into the mold — not applied after the fact — so the detail holds up whether you're looking at it across the room or under a lamp. Read the full forging story for how this one came together.

Choose Your Display

Blade only, or add a Small Stand (+$2), Large Stand (+$3), or Vertical Stand (+$4) — all three are shown in the gallery, and given its long, slender profile, the vertical mount tends to show this one off best. It's not meant to stand alone: pair it with Windcleaver for the matching curved-and-straight duo, wander the rest of the Courage & Wisdom Blade Vault ）, or browse every sword we've forged .

Free worldwide tracked shipping (US orders land in 10–14 days), a foam-lined gift box, and a 30-day money-back guarantee come standard on every order. Two blades, one shrine, one shelf that's about to get more interesting.
