The Opinal #6 is the smallest Opinal knife making it ideal for outdoor activities, sports or daily manual work such as sewing or small crafts. The carbon steel blade is extremely hard guaranteeing excellent cutting quality, good wear resistance and easy regrinding which is all beautifully supported by a beechwood handle. The No.6 Opinel has a vibroloc safety ring which can lock the blade open while in use and closed making it safe during transport.
