About Us

The Origin: Born from Curiosity, Forged in Titanium

In 2020, our founder, Dan Sun, was a relatively new technical diver, yet she possessed an intense curiosity about how our equipment enables us to safely explore alien worlds. Juggling single tanks, twins, and sidemount configurations, she quickly realized she needed a reliable tool for quick adjustments on the go. She sought out the legendary stainless steel Sea Spanner, only to be frustrated by its disappearance from the market.

Like many divers facing the same void, Dan spent countless hours researching alternatives. She quickly learned that tools made of rust-proof materials, like 316 stainless steel, were surprisingly rare. Then, during a late-night online deep dive, she stumbled upon the bicycle community’s obsession with titanium. Captivated by their demand for ultra-lightweight, rust-free tools, she wondered: Why isn’t this alloy the standard in the diving world?

Armed with research on titanium’s characteristics, Dan made two pivotal decisions. First, she would pursue titanium alloy over 316 stainless steel as the ultimate material for dive tools. Second, if the market wouldn't provide it, she would fund the production herself, leveraging connections from the high-end bicycle manufacturing world. At the time, she had a comfortable corporate career and no idea that this midnight eureka moment would completely derail her path into full-time dive equipment manufacturing.

Much like iconic late cave diver Forrest Wilson, who hand-made the first 100 cave arrows when nobody thought the world needed them, Dan took a leap of faith. She produced a first batch of just 30 titanium spanners, unsure if anyone would pay a premium for a niche tool. The rest is history: her spanners quickly became a staple, widely used and deeply appreciated by the global technical and scientific diving community.

It wasn’t a grand corporate strategy or deep capital that built this brand. It was simply a maker’s spirit: If the perfect tool doesn’t exist, create one—even if it isn’t perfect yet.

Light, Robust, Anti-Rust

Over the years, beyond the typical manufacturing and logistical hurdles, we’ve established a clear philosophy on how we approach creation:

Material First: We think outside the box, prioritizing top-tier performance materials over common, cost-cutting alternatives.
Agile & Field-Tested: Our ideas are born in the field. We iterate in small volumes, collaborating directly with divers to refine our gear based on practical, real-world usage.
Functional Styling: We believe dive gear should be aesthetically pleasing. We strive for a sleek, minimal design that brings joy to the diver without ever compromising the technical core.

Early on, we nailed our slogan: Light, robust, and anti-rust. "Light" and "Anti-rust" drive our relentless search for superior materials, while "Robust" grounds us in the uncompromising safety and quality required for diving. But today, we offer so much more than just those three words.

As our founder often says, “We don’t always get it right. At least, not at the beginning.”

But we remain grounded by our own diverse technical diving experiences and our deep connections to global dive communities—from caves and deep wrecks to tropical reefs and cold-water environments.

The Future: Scaling with Soul

Our agility in product development, access to like-minded suppliers, and openness to niche ideas continue to open doors for endless collaborations.

We are always looking for new ideas and feedback. If we haven’t replied to you recently, it’s simply because we’ve been stretched thin by overwhelming demand.

We also hear your requests for a better shopping experience, and we are actively working to scale our operations to serve you better.

Frankly, we never set out to be an industry leader in market share. Our ambition has always been simpler: to fill the gap for technical divers and to be the beloved brand that relentlessly explores and iterates on the equipment we rely on.

At the end of the day, we are unapologetic nerds, obsessed with building the best tools out there.

We deeply appreciate every single person who has brought us to where we are today.
