GiantMouse is known for creating knives with bold design language, clean geometry, and production runs that never overstay their welcome.
Now, they’ve added another knife to their fixed-blade lineup with the release of the GMF1-XL Black Dunes, a stealthy, sculptural, limited-run variation of the already-popular GMF1-XL platform.
With only 175 units being made, this is the kind of drop that feels less like a knife launch and more like an insider release.
And if your Everyday Carry (EDC) gravitates toward minimalism with a tactical edge, this one’s going to hit all the right notes.
At the heart of the Black Dunes is a sweeping set of Fat Carbon black scales, textured like shifting sand under moonlight.
It’s a finish that gives this GMF1-XL variant its name, and its mood.
The blade itself is forged from Vanadis tool steel, hardened and given a dark PVD finish to match the handle’s tone.
It’s tough, wear-resistant, and holds a razor edge, perfect for users who put their knives through daily paces but want something that stands out from the usual lineup of overbuilt EDC tools.
This XL version scales up from the original GMF1, giving users more handle to work with, without tipping into bulky territory.
It’s still compact, but balanced, light in the hand, quick to maneuver, and easy to conceal or stow.
Like the rest of GiantMouse’s fixed-blade line, the GMF1-XL Black Dunes is built to be used.
But that doesn’t mean it doesn’t deserve a spot on your display shelf.
The tight tolerances, sleek lines, and monochrome palette make this feel like a designer piece that just happens to be razor sharp.
The included black leather sheath keeps the silhouette clean and refined, equally suited to camp-carry or minimalist desk knife vibes.
Whether you’re slicing cordage, whittling wood, or just admiring the fit and finish, this blade feels like a statement.
If your everyday carry kit leans dark, refined, and tactical, the GMF1-XL Black Dunes is a worthy upgrade.
It’s more than a steel-and-carbon tool, it’s a limited-edition drop that bridges the gap between function and art.
With only 175 made, this one won’t stick around long. And like any good GiantMouse release, once it’s gone, it’s truly gone. Available October 23, 2025 for $325, only at GiantMouse.com.
