Carbon Steel — Opinel

The Carbon collection is Opinel's historic pocket knife range and one of the best-sellers on AZ boutique. It carries the original blade invented by Joseph Opinel in 1890: a non-stainless carbon steel renowned for its exceptional edge, mounted on a French beechwood handle.

The Carbon collection's specificity

Carbon steel is Opinel's historic steel: it sharpens easily, holds an edge better than many stainless steels, and develops over time a recognisable grey patina. The beechwood handle, the folding blade and the Virobloc safety ring (from the n°6 upwards) are the other signatures of the collection.

• Carbon steel blade, superior sharpness and edge retention
• French beechwood handle
• Virobloc safety ring from the n°6 (locks the blade open and closed)
• Made in France, in Chambéry (Savoie)

The most popular pieces in the Carbon collection

A few sizes account for most of the purchases on AZ boutique, around the iconic n°8.

• Opinel Carbon n°8 (8.5 cm blade): AZ boutique's best-selling piece, the brand's flagship size, versatile for picnics, hiking and everyday use
• Opinel Carbon n°7 (8 cm blade): more compact, ideal for detailed work and daily carry
• Opinel Carbon n°6 (7 cm blade): small and light, for pocket or handbag
• Opinel Carbon n°9 (9 cm blade): reinforced version for DIY and demanding tasks
• Opinel Carbon n°12 (12 cm blade): the large blade, for heavy and outdoor work

Choosing within the Carbon collection

Why is the Carbon collection well-known?

It is Opinel's original collection: the carbon steel blade is the one Joseph Opinel has fitted since 1890. It remains the favourite among purists for its sharpness, ease of sharpening and characteristic patina. The Carbon n°8 is the brand's iconic pocket knife.

Carbon or Stainless: which to choose?

Carbon steel offers a sharper edge and sharpens more easily, but requires regular care: the blade patinas and can rust if left damp. Stainless steel requires less maintenance but takes a slightly less fine edge. Carbon is recommended for knife enthusiasts; stainless for damp uses (fishing, beach, seaside picnics).

Which size should I start with?

The n°8 is the natural entry point: it is the reference size, versatile for picnics, hiking, foraging and small tasks. The n°7 or n°6 suits more everyday pocket use. The n°9 and n°12 are recommended for DIY, gardening or heavier outdoor work.

How do I care for an Opinel Carbon?

No dishwasher: the blade would oxidise. Wipe the blade after every use, especially after cutting damp or acidic foods (fruit, meat). A light coating of food-safe oil (or maintenance oil) on the blade slows down patina. The grey patina that develops over time is not a defect: it protects the steel and is part of the knife's identity.
