Size Comparison
Overview of Dimensions
The Exo-M is not your average EDC knife. Let’s first talk about size. It sits in a great sweet spot for those who want a medium-sized carry, but it’s always good to compare it to some other well-known models for context. Here’s how the Exo-M stacks up:
| Knife Model | Blade Length | Handle Length | Overall Length |
|---|---|---|---|
| Exo-M Gravity Knife | 3.5 inches | 4.6 inches | 8.1 inches |
| Spyderco PM2 | 3.44 inches | 4.81 inches | 8.25 inches |
| Ontario Rat Number Two | 3 inches | 4.1 inches | 7.1 inches |
| Spyderco Delica | 2.9 inches | 4.25 inches | 7.15 inches |
As you can see, the Exo-M fits comfortably between some of the most popular knives like the PM2 and Delica. It’s a great option for those looking for something compact but not too small.
Aesthetics and Design
Rayat, the designer behind the Exo-M, is known for creating knives that are both functional and stylish. The Exo-M continues this tradition, sporting a sleek and tactical design. The burlap Micarta handle not only looks rugged but also provides excellent grip. The knife’s compact form factor makes it a top choice for urban everyday carry (EDC).
The Designer and Brand Background
Overview of Rayat Knives
For those unfamiliar with Rayat, it’s a Chinese knife manufacturer with a reputation for high-quality, innovative designs. Their knives have garnered a following among enthusiasts for their premium materials and attention to detail.
Introduction to the Designer
Rayat’s Exo-M Gravity Knife is designed by the same creator responsible for the popular Rayon XO. Known for their attention to both aesthetics and practicality, the designer has developed a series of knives that appeal to both collectors and EDC users. The Exo-M fits seamlessly into this lineup, with a balance of unique functionality and everyday usability.
Mechanics and Operation
True Gravity Knife Functionality
So what exactly is a gravity knife? Simply put, it’s a knife where the blade is deployed using the force of gravity. The Exo-M employs a slider mechanism that allows the blade to drop open when you tilt the knife downward and slide the mechanism. It’s an intuitive design once you get the hang of it, making it one of the smoothest-opening knives out there.
It’s important to mention that gravity knives can fall under legal restrictions in various places. In California, for example, gravity knives are often prohibited for carry in public. Be sure to check your local laws before purchasing or carrying the Exo-M.
Safety Features
The Exo-M comes with a built-in safety feature that prevents accidental deployment. The slider mechanism locks in place when the blade is retracted, ensuring the knife won’t open unexpectedly. This feature makes the Exo-M a solid choice for users who prioritize safety in their EDC gear.
User Experience
If you’re new to gravity knives, there’s a bit of a learning curve. The deployment method is different from your standard folding or automatic knives, but after a few uses, it becomes second nature. The knife’s balance and weight distribution also make it easy to control during use.
Performance Analysis
Blade Quality and Options
The Exo-M comes with multiple blade styles, including Tanto, double-edged dagger, and drop point. CPM 3V steel is used for the blade, known for its exceptional toughness and edge retention. It’s a premium material that ensures the knife will hold up under rigorous use.
Here’s a quick comparison of the available blade options:
| Blade Style | Best Use | Pros | Cons |
|---|---|---|---|
| Tanto | Tactical | Strong tip, piercing capability | Limited slicing capabilities |
| Double-edged Dagger | Combat/self-defense | Double-edge for quick cuts | Harder to sharpen |
| Drop Point | All-around | Great for slicing, versatile | Less piercing strength |
Edge Retention and Sharpness
In my tests, the Exo-M’s edge retention was top-notch. After weeks of everyday tasks—cutting cardboard, food prep, and light wood carving—the blade maintained its sharpness remarkably well. Regular stropping is all that’s needed to keep it razor-sharp.
Texturing and Grip
The burlap Micarta scales provide both a secure grip and a unique aesthetic. Even in wet conditions, the textured surface ensures the knife stays firmly in hand. This is crucial for a knife that could be used in tactical or high-stress situations where a slip could have serious consequences.
Action and Deployment
User Interaction
The action on the Exo-M is where it truly shines. The gravity deployment is not only fun to use but incredibly practical. Once you get used to it, deploying the blade becomes quick and smooth. The mechanism feels solid, with no noticeable play or looseness, which is crucial for a knife that relies on moving parts.
Fidget Factor
Let’s face it, a lot of us love knives for their fidget factor, and the Exo-M does not disappoint. The unique slider mechanism offers a satisfying and tactile experience, making it a great knife for those who enjoy the act of opening and closing their blades.
Pros
✅Compact size: The Exo-M is perfect for urban EDC, providing a balance of utility and portability.
✅Blade options: With multiple blade styles, there’s an option for everyone.
✅Safety mechanism: The slider lock prevents accidental deployments, ensuring safe carry.
✅Solid action: The gravity mechanism works smoothly, making it a joy to use.
Cons
⛔Limited tactical use: While the Exo-M is great for EDC, its gravity deployment mechanism may not be ideal for all tactical situations.
⛔Price: At $285, the Exo-M is on the pricier side, which may be a barrier for some buyers.
Conclusion
In conclusion, the Exo-M Gravity Knife is a standout in the world of gravity knives. Its unique deployment mechanism, premium materials, and compact design make it a top choice for those who want something different in their EDC rotation. However, potential buyers should be aware of the legal implications and price before making their purchase. For those who can legally carry it and appreciate innovative design, the Exo-M is well worth the investment.
