How we engineer
The same four questions get asked of every tool before it goes into tooling.
Does the number that matters get published?
Airflow volume and velocity for a dryer. Stroke rate under load for a clipper. Not the number that is easiest to raise, the number that decides the result.
Where does the mass sit?
A tool is held for eight minutes at a time. Balance point matters more than total weight, which is why the dryer motor lives in the handle even though that is the harder place to put it.
What wears out, and can you buy it?
Every wear surface gets a part number before the tool ships, and a stocking commitment of ten years from launch. If we cannot commit to that, the part gets redesigned.
Can it be opened?
Screws rather than glue wherever the assembly allows it, so a blade set or a filter carrier is a two-minute job rather than a warranty claim.
