“Densely compressed filaments laid down over a continuous metal channel.”
Hand

“Individual tufts of filament are drawn through holes in the base and tied off.”
The filament decides
how hard it works.

Halfway is
where it binds.
“The brush diameter is too large relative to the tube's inner diameter.”Schaefer Brush, “When Tube Brushes Bind”
Taper the tip.
A smaller tip lowers entry resistance. Bristles engage progressively and self-center.
Match the diameter.
A slight diameter reduction may be all the tube needs.
Read the engineering note
“Listen. Engineer. Build. Improve.”
Hot tube.
Wrong filament.
Heat changes the choice. A filament that fails in heat can shed and stop cutting.
