Our take on the Opinel No.9 Carbon Steel Folding Knife

The Opinel No.9 is a French folding pocket knife with a 9 cm carbon steel Yatagan blade and a varnished beech wood handle. It weighs 2.0 oz and opens two-handed with a nail nick, with no lock ring on this size. Carbon steel takes a very sharp edge and holds it well, but it will rust without care and darkens into a patina with use. At $20.99 at Shelter Institute as of November 4, 2026, it sits at the low end of its recent price range across the three stores that carry it new.

Questions and answers

Is the Opinel No.9 worth it?
Yes, if you want a sharp, light folding knife for about $20 and will keep the carbon blade dry and oiled. It is a simple tool, not a one-hand or locking knife.
Does the No.9 have a locking ring?
No. The No.9 has no Virobloc lock, so the blade can fold during use. If you want a lock, look at the No.8 or other locking Opinel models.
How does the No.9 compare with the No.8?
The No.9 has a 9 cm blade and is slightly larger than the No.8's 8.5 cm. The No.9 also lacks the lock ring that the No.8 carries, so the No.8 is the safer choice for harder cutting.
Will the carbon steel blade rust?
Yes, it can corrode. Wipe it dry after use and oil it lightly; the blade will darken into a patina, which is normal and protects the steel.
What is in the box?
The knife itself. Opinel ships it in simple cardboard packaging with no sheath or sharpener included.
When is it cheapest?
The best new price was $20.99 at Shelter Institute as of November 4, 2026, at the low end of its recent range. Watch for drops around hunting season and holiday sales.
