Who Makes a Good Assisted Folding Knife: A Comprehensive Guide
Assisted folding knives have become increasingly popular among knife enthusiasts, outdoor adventurers, and everyday carry (EDC) users due to their perfect balance of safety, convenience, and quick deployment. Unlike automatic knives that open with the press of a button, assisted opening knives require a slight push on the blade before the spring mechanism takes over, making them legal in more jurisdictions while still offering rapid one-handed operation. But with so many manufacturers in the market, who truly makes a good assisted folding knife? Let’s examine the top contenders and what makes their products stand out.

The best assisted knives open smoothly and consistently without being overly stiff or loose. Look for:
- Reliable spring mechanism
- Smooth pivot action (often aided by bearings or washers)
- Properly tuned tension
2. Blade Quality

- Proper heat treatment
- Edge geometry suitable for intended use
- Corrosion resistance if needed
3. Locking Mechanism
A good lock is crucial for safety:
- Frame locks
- Liner locks
- AXIS-style locks
- Should engage fully and securely
4. Ergonomics
- Comfortable handle material (G-10, aluminum, etc.)
- Good grip texture
- Balanced weight
- Appropriate size for intended use
5. Build Quality
- Tight tolerances
- No blade play
- Quality hardware
- Durable construction
6. Legal Compliance
Since laws vary by location, good manufacturers often offer:
- State-compliant versions
- Clear specifications on blade length
- Appropriate mechanisms for regulated areas
Price Considerations
Assisted opening knives span a wide price range:
- Budget ($20-$50): CRKT, some Kershaws
- Mid-range ($50-$150): Most Kershaw, SOG, some Benchmade
- Premium ($150+): Zero Tolerance, higher-end Benchmade
While you generally get what you pay for, there are excellent values at every price point.
Maintenance Requirements
Good assisted knives should:
