Early 20th century currier's knife manufactured by Nicolai Clasen, Hamburg, Germany.
A currier is a specialist in the leather-processing trade. After the tanning process, the currier[1] applies techniques of dressing, finishing and colouring to a tanned hide to make it strong, flexible and waterproof.[2]
The leather is stretched and burnished to produce a uniform thickness and suppleness, and dyeing and other chemical finishes give the leather its desired colour.
