Why NULU Works According to an OT and a PT
Megan Smith, PT and Mike Price, OT, CIO/CMO breakk down the biomechanics behind adaptive knife design — and why it matters for people with arthritis, reduced grip strength, or upper extremity limitations.
We've been on RehabMart for months — and we are proud to be part of their trusted adaptive catalog. But something just changed: physical therapist Megan Smith, PT and Mike Price, OT, CIO/CMO published a dedicated clinical article analyzing NULU, providing the kind of third-party clinical validation that no marketing campaign can replicate.
Megan doesn't just describe the knife — she explains the biomechanical why. She details why standard chef's knives place unnecessary strain on weak joints, and how NULU's Force Transfer Geometry™ changes the way cutting energy is distributed through the arm.
Key Clinical Takeaways
The Wrist Problem
Traditional knives place the hand behind the blade, forcing the wrist to torque and absorb cutting pressure.
Force Transfer
NULU's centered handle directs cutting force through the forearm and shoulder while keeping wrists in neutral.
Four Grip Positions
Allows users to switch grip styles depending on ingredient density, cutting technique, and personal comfort.
Versatile Arc Blade
The 160° continuous curved blade handles chopping, mincing, rocking, and shaving with one accessible tool.
I developed NULU out of necessity. Living with multi-joint arthritis across my hands, wrists, and body made conventional meal prep painful and exhausting. I didn't want to stop cooking — I wanted a tool built around changing physical ability rather than expecting the cook to compensate for poor tool mechanics.
Having a licensed physical therapist affirm those exact design principles is an incredible milestone for our community.
Clinical Review & Available Systems
"For someone with reduced hand strength, limited dexterity, arthritis, or other upper extremity limitations, standard mechanics can make even basic food preparation tiring... The NULU Adaptive Kitchen Knife combines the curved profile of a traditional ulu knife with an unconventional handle position designed to transfer cutting force more directly through the hand and arm."
