What Size Opinel Knife Is Ideal for Everyday Carry? 

For anyone who loves adventure, a reliable knife is one of those essentials you just can’t do without. 

Whether you’re exploring Opinel Sizethe wilderness, camping under the stars, or hiking on your favorite trail, a trusty blade can make all the difference. When it comes to knives that are as functional as they are iconic, Opinel is a name that stands out. But with so many different sizes of these knives, it can be tough to figure out which one is best suited for your everyday carry (EDC).

In this blog, we will be diving into the world of Opinel knives to help you figure out which size will be your perfect companion on your next adventure. Let’s explore what makes each size unique and how to choose the right one for your needs.

Opinel Knives Size Breakdown

These knives come in several sizes, each identified by a number. These numbers correspond to the length of the blade in centimeters, but the handle size also changes with each model. 

While the numbers go all the way from No. 2 to No. 12, this blog focuses on the sizes most suited for everyday carry: No. 6, No. 7, No. 8, and No. 9. Each one has its strengths depending on what you’re looking for in a knife. 

No. 6: Small and Stealthy

If you want something that’s easy to carry and doesn’t weigh you down, the Opinel No. 6 is the way to go. This knife is compact and low-profile, making it perfect for those who prefer to keep things light. It’s the kind of knife you can carry all day without even noticing it’s there. 

Whether you’re opening packages, whittling sticks, or slicing through fruit on a lunch break, the No. 6 gets the job done with ease.

This knife is ideal if you’re all about portability. It fits into your pocket without creating any bulk and is small enough to make using it feel like second nature.

No. 7: The Sweet Spot

Step up to the No. 7, and you get a knife with more cutting power. This knife offers a nice middle ground between the ultra-portable No. 6 and the more robust No. 8. 

The extra length gives you more versatility without making the knife feel cumbersome. Whether you’re doing light camp chores, carving a walking stick, or slicing through some rope, the No. 7 has the chops to handle a variety of tasks.

If you’re after a knife that can do more than just basic chores but still want something that’s not too big, the No. 7 is the perfect choice. It's like having a reliable tool that does a little bit of everything.

No. 8: The All-Purpose Hero

The No. 8 is the go-to size for most adventure enthusiasts. This knife is big enough to handle more demanding tasks but still small enough to easily slide into your pocket. 

It’s the knife that can handle everything from food prep to light survival tasks. It’s also small enough to be discreet, so you won’t be walking around with something that feels too bulky for everyday carry.

This size is the most popular among all, as it strikes a perfect balance between utility and portability. If you value versatility and need a reliable all-around blade, the No. 8 is your ideal companion.

No. 9: For the Bigger Jobs

The No. 9 packs a bit more punch for those who need a little extra muscle. While still a compact knife, it’s better suited for those who need a tool for tougher tasks. 

If you spend a lot of time camping or hunting, or you need a blade that can handle chopping wood or cutting through thicker materials, the No. 9 offers extra cutting power.

It’s a solid choice for anyone who needs a heavier-duty tool but doesn’t want to carry something too large. If you’re not as concerned with size and are looking for a knife to take on more demanding jobs, the No. 9 has your back.

Choose the Right Size For Yourself

Ultimately, an Opinel knife is more than just a tool — it’s a reliable companion for any adventure you embark on. 

Whether you’re in the city or the backcountry, having the right knife can make everything easier and more enjoyable. Each size serves a different purpose, so think about your needs beforehand and choose accordingly. 

In addition to the sizes mentioned in this blog, if you are looking for another model, there is a variety available on our website and in-store. You can get your hands on any Opinel you desire.

No matter which size you choose, an Opinel knife will be a reliable, functional, and stylish addition to your everyday carry.
