We turn the barrel of this driver wider than our standard patterns. The 1 mm blade seats into small movement screws where fingertips need a broader purchase to break or set thread without excessive downward force. The swiveling head stays parked under your index finger while the body turns between thumb and forefinger.
Wide drum body
The enlarged barrel changes the lever arm between your fingers. You turn a movement screw with less pinch pressure on the knurling, which helps when setting delicate bridge screws or stubborn ratchet wheels.
Parallel blade tip
We grind the 1 mm tip flat on both faces so it fills the screw slot evenly across the bottom. That flat contact spreads the turning force rather than concentrating it at the top edges of the slot.
Smooth swivel head
The black cap turns on a central pivot while you hold it down with one finger. It keeps the driver vertical on the movement while your lower fingers rotate the knurled barrel.
Replacing worn blades
A side setscrew locks the blade shank into the body. Loosen it with an auxiliary driver to pull a chipped blade and slide a fresh 1 mm factory blade into the bore.

A note that touches this tool
Reading a catalogue number
What the parts of a Bergeon reference number mean, why the number is how a tool is asked for, how a suffix marks a size or a variant of the same family, and how to find the spare blade for a handle you already own.
Choosing a blade width
Why a screwdriver is chosen by the width of its blade rather than by its name, what happens to a screw head when the blade is a step too narrow, how the blades are stepped through the range, and how a worn blade is dressed or swapped.
