Intro to Opinel knife Modification: Part 1

Opinel knives are currently offered in eleven numbered sizes: 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, and 13. The No. 1 Opinel was discontinued in 1932.

More History

The main sizes that I modify are 9, 10, and 12.

I find there is a little more meat on the blade and the handle to work with.  The No.12 is a beast.  Just the piece of steel is pretty impressive. I have not modified a N0.13 yet.

I have modded a couple of 7’s.

I like both the carbone and stainless blades.

When modding a carbone, there is an extra design element to play with in the blade patina process.

No. 10 “Opi-Fighter” Vinegar and Mustard Patina

The No.8’s that I modify are usually the raw handle Ebauche.

I have enjoyed working on a stock oak and walnut handle No. 8 also.

The oak  handle “Oliver Twist” is about to be the giveaway when I reach 1000 followers on BladeObsessionOne.


If you are buying your first Opinel, the classic No. 8 is always a great start.  It is their most versatile and most sold size. It will give you the appreciation of the design and quality of these knives. It is in the middle of all the sizes and is a perfect picnic or cheese knife. In my opinion, as far as a pocket folders go, this knife is one of the best tools you can buy for around $12.

I use a Lansky sharpener and I get my blades razor sharp.

For a really light blade, my favorite carry is a No. 6  with an olive wood handle.  The No. 6 is the smallest Opinel with the Virobloc locking design.
