What it is

A folding knife with a steel blade and wooden handle, of simple, cheap design, which Joseph Opinel produced in series from 1890. In 1955 a safety ring (virole) was added to lock the open blade.

Folding knives are far older (Roman); what is recorded is Opinel's cheap industrial production. The date of 1890 is that of the first production, according to the company.

What it led to

  • an affordable pocket knife for farmers, shepherds and mountaineers
  • ring-locking folding knives
  • an emblematic brand of French cutlery
