A seam is where water gets in
Every other brush has two: one where the head meets the body, one where the body meets the base. This one keeps only the first, as a steel-lined bayonet, because its head is meant to come away. The handle has none. Forty minutes on a five-axis lathe, forty more at the finishing bench.
A quarter turn, and it comes away
The bristles are the only part that wears, so they are the only part that comes off. They sit on a cartridge, locked into the titanium head by a bayonet.
- Release90°
A quarter turn frees the two lugs of the cartridge from the bayonet. It then lifts straight off.
- SeatCopper mark
The notch in the new cartridge meets the copper mark just below the bayonet. Press it home and turn it back a quarter.
- Wear9 tufts
The blue centre row fades as the bristles wear. Once it has faded, the head is due.
- Kept7 ridges
The tongue cleaner on the back belongs to the handle, not to the cartridge, and stays. So does the bayonet, guaranteed for life.
Forty handles, or one
A plastic brush is thrown away four times a year, handle and all. This one replaces the head on that same cadence and keeps the handle. Ten years is forty handles, or one.
The difference is the last forty minutes
Numbered before it is finished
The serial is cut into the base while the handle is still on the lathe. Registration puts that number against one name, and the guarantee stays with the name rather than with the object.
