Fierce Deity Sword Replica – 21cm Die-Cast Metal | The Blade the Moon Remembers

Filmed on a miniature set we build by hand for each piece — the weight in the hand, the scale against everyday objects, the die-cast detail up close. No CGI, no stock footage.

BlacksmithSONG casts the Fierce Deity Sword replica in solid die-cast zinc alloy — 21cm (8.3"), 71g (2.5 oz), free worldwide tracked shipping. It's the lightest blade we've made so far — which feels almost unfair, considering what it's supposed to be capable of.

What Is the Fierce Deity Sword?

The Fierce Deity Sword belongs to a legendary green-clad hero's rarest transformation — a masked, god-like form unlocked deep in a story where an impossibly close moon counts down to something terrible. In its home game, the blade is famous for firing pure energy off its double-helix edge with every swing. Here, it's cast in solid metal — no beam attack included, but the silhouette is unmistakable.

The Scene: Beneath the Falling Moon

We built this set around the story where this sword first appeared — a mossy clearing scattered with unsettling carved masks: a horned, spike-crowned one with glowing eyes, a grinning pig-snouted one, a red-striped screamer half-hidden in the rocks, and a small blue ocarina resting nearby like someone just set it down mid-song. Somewhere above it all, an eerie, too-close moon watches. Every photo on this page is a real shot inside that handcrafted set — no CGI, no renders. For the story behind hunting down four different mask sculpts for this set, we wrote up the whole build .

What You're Holding

21cm in the Real World

Close to the length of a chef's kitchen knife, handle included — but at just 71g (2.5 oz), it's lighter than you'd expect, more letter-opener than legendary weapon. That lightness isn't a flaw; the real double-helix blade was never meant to feel like a slab of steel. The handheld photo above shows exactly how it sits in the palm.

Straight from the Mold

This one's cast as a single zinc-alloy body, twin blades and all — the negative-space opening between the prongs and the crosshatched grip wrap are both shaped directly into the mold, not assembled from separate pieces. We hand-apply the teal-to-green gradient afterward, blade by blade, so no two finishes catch the light quite the same way.

Choose Your Display

Sword alone, or add a Small Stand (+$2), Large Stand (+$3), or Vertical Stand (+$4). Given how slim and symmetrical this blade is, the Vertical Stand suits it best — it lets the double-helix opening catch light from both sides instead of hiding one against a base.

A certain green-clad hero doesn't stop at one legendary blade — if the Master Sword replica already anchors your shelf, this one adds the darker, stranger half of the collection. Browse the rest of the Courage & Wisdom Blade Vault , or see every sword we've cast .
