Affordable Excellence with the FUNBRO Tanto
In our side-by-side evaluations, the FUNBRO EDC surprised us by offering features usually found on knives twice its price, such as a ball-bearing pivot. While it uses 7CR13Mov steel—which is softer than D2—it outperforms many others in its price bracket due to its superior tanto geometry. We found that the tanto tip is exceptionally robust, making it much better for prying and piercing than the spear points we tested.
Blade: 7CR13Mov Steel, Tanto Profile, Ball Bearing Pivot, Glass Breaker
PROS:
* Ball bearing pivot creates an incredibly smooth, fluid opening action.
* Tanto blade shape is significantly stronger at the tip for heavy-duty piercing.
* Highly cost-effective, making it an excellent “beater” knife for rough tasks.
* Excellent corrosion resistance makes it low-maintenance for casual users.
CONS:
* Steel quality is lower, requiring very frequent touch-ups on a stone.
* The handle texture can be somewhat abrasive on the palm during long sessions.
We Tested:
We put this knife through a “warehouse week,” opening hundreds of cardboard boxes and cutting through thick plastic strapping. We found that while the edge rolled slightly more than the D2 blades, the smooth flipper action remained flawless. It’s a snappy, fun knife to use that doesn’t make you feel guilty if you scratch it up.
WHO SHOULD BUY THIS:
This is our top recommendation for a budget-conscious buyer or someone looking for a great gift. It’s perfect for the person who needs a “utility” blade they aren’t afraid to use and abuse on a daily basis.
Best Automatic Knife Comparison Insights
When looking at our top three selections, the Smith & Wesson MPOTF10 is clearly the best choice for tactical and emergency use due to its glass breaker and OTF action. In contrast, the Outdoor Jump Knife with D2 Steel is the best for pure cutting endurance, as its D2 steel is significantly harder and holds an edge longer than the S&W’s AUS-8. The FUNBRO EDC serves as the best budget-friendly entry point, offering the smoothest deployment thanks to its ball-bearing pivot, even if the steel requires more frequent sharpening.
We found that while the Jump Knife offers the best mechanical value for heavy work, the Smith & Wesson provides the most safety features for daily carry. If your priority is a strong piercing tip, the FUNBRO’s tanto shape outperforms the others, but for slicing and food prep, the Jump Knife’s flat grind is the superior geometry.
What We Look for in Best Automatic Knife
When we evaluate any potential best automatic knife, our team prioritizes the synergy between steel quality and deployment reliability. We look for blades that use at least D2 or AUS-8 steel at a minimum, as anything lower often fails to hold an edge during professional use. Our team recommends checking for a “dead-centered” blade and a pivot that operates without grit or friction.
We also focus heavily on the lock-up security. During our testing, we look for zero “blade play”—that annoying wiggle some knives have when open. A high-value knife must feel like a fixed blade once it is deployed. We prefer handle materials like G10 or aircraft-grade aluminum, as these provide the long-term durability our readers expect.
How We Choose the Right Best Automatic Knife
Our selection process begins with a “value-to-performance” audit. We don’t just look at the price tag; we look at what that price buys you in terms of steel longevity and ease of maintenance. We choose knives that can be easily serviced by the user, such as those with standard Torx screw constructions.
Finally, we consider the intended environment. For our budget-conscious recommendations, we select tools that are versatile enough to handle both a warehouse floor and a camping trip. We recommend choosing based on your most frequent task—if you cut a lot of boxes, go for the tanto; if you need a life-saving tool, go for the S&W with the glass breaker.
Best Automatic Knife Frequently Asked Questions
How Much Should We Spend on the Best Automatic Knife?
We found that the “sweet spot” for a reliable automatic or assisted knife is usually between $30 and $70. In this range, our team sees a significant jump in steel quality (like D2) and handle durability. While you can spend more for premium steels, these mid-range options provide the best return on investment for daily users.
Is D2 steel better than stainless steel for a daily blade?
D2 steel is a “semi-stainless” tool steel that offers much better wear resistance than common stainless steels like 420 or 7CR13Mov. However, we found it is more prone to spotting if not wiped down after use. If you work in wet environments, a high-grade stainless like AUS-8 might be a more convenient choice.
What is the advantage of a tanto blade profile?
The tanto profile, like the one on the FUNBRO we tested, moves the bulk of the steel toward the tip. This makes it much harder to snap the point when prying or piercing tough materials. We recommend this shape for industrial work, though it is slightly harder to sharpen than a curved drop point.
How do we maintain the action on an automatic knife?
Our team recommends a light application of high-quality pivot oil every few months. We found that blowing out the handle with compressed air is essential to remove pocket lint, which is the number one cause of deployment failure in automatic tools.
Why is a safety lock important for these tools?
A safety lock, like the one found on the Smith & Wesson MPOTF10, prevents the blade from deploying while in your pocket. Because automatic knives are spring-loaded, this feature is vital for budget-conscious buyers who want to ensure their gear doesn’t cause accidental injury or damage to their clothing.
