The binary disabled/able-bodied model is costing businesses billions in invisible markets. The Ability Curve Model offers a better framework — and a bigger opportunity.
98% of food service workers report musculoskeletal pain. The culprit? A kinetic chain broken by traditional knife design. Here's the biomechanics — and the fix.
Seated cutting fails because traditional knives break the kinetic chain. Peer-reviewed research and circular geometry explain why — and how NULU restores it.
One NULU knife replaces six. For commercial kitchens, that means measurable labor savings, fewer injuries, and up to $4,500 back annually. Here's the math.
The adaptive market doesn't lack innovation — it lacks connective infrastructure. One founder's case for why building better systems matters more than building better product
In this episode, Doug Katz and Gordon Downey discuss how engineering and industrial design intersect to create the NULU knife—an adaptive kitchen tool inspired by the traditional ulu. By replacing grip-dependent cutting with a controlled rocking motion, the NULU knife reduces wrist strain and fatigue, making food preparation more accessible for people with arthritis, injuries, or limited hand strength while remaining effective for serious cooks.
My appearance on Behind the Numbers: why NULU pivoted 360 degrees back to adaptive — and why perseverance is the boat, every lesson is the wake, and the over-50 team is the trade secret.
NULU’s adaptive kitchen knife is now available through over 36 state assistive technology lending libraries, expanding access to hands-on evaluation for individuals with disabilities, older adults, and clinicians nationwide.
A severe flare-up sparked a kitchen revolution. Disabled veteran Doug Katz tells The Chronic Truth how NULU's adaptive knife eliminates grip strain for good.
A reviewer called NULU "an overpriced pizza cutter." He even called it dangerous. Here's why that criticism reveals exactly why universal design faces headwinds — and why it matters anyway.
My appearance on The Chronic Truth Podcast: MS, the kinetic chain, and why everyone is one second from a diagnosis — and one adaptive tool from staying independent in the kitchen.
We design for peak ability and call it universal. But ability changes — and if we live long enough, we all become the people we're designing around.
