When the pins bend, the tips lose their rounding or a deshedding edge stops lifting hair — a bent pin scratches, and a blunt edge pulls instead of cutting.
Brushes wear slowly and are replaced late.
Pin brushes
Look at the tips. Rounded is correct; worn to a point is a scratch waiting to happen. Bent pins pull rather than comb.
Deshedding edges
They dull. The symptom is a tool that pulls the coat and removes less per pass, which people mistake for the dog shedding less.
Self-cleaning brushes
The ejection mechanism is the part that fails — a button that no longer retracts the pins turns a two-second job into picking hair out by hand.
Cost, in context
These are €10 to €30 tools used weekly for years. Replacing one that has gone blunt is cheaper than the session it ruins.
