The Ultimate Buying Guide for OTF Knives
Out-the-Front (OTF) knives are cool tools. They shoot their blade straight out and retract it just as fast. Buying one can be tricky. This guide helps you pick the best OTF knife for you.
Key Features to Look For
When you shop for an OTF knife, look closely at these main parts. These features decide how well the knife works.
Blade Deployment Mechanism
- Single Action (SA): You push a button to fire the blade out. You must use another action, like pulling a slider, to bring it back in. These are usually simpler and cheaper.
- Double Action (DA): This is the top choice for many. You push the button one way to shoot the blade out, and push it the other way (or pull the slider back) to retract it. This offers faster, smoother action.
Blade Locking System
A good OTF knife locks the blade securely open. You need a strong lock so the blade does not accidentally close while you are using it. Check reviews to see if the lock feels solid.
Safety Features
Since OTFs are fast, safety matters a lot. Good knives have safety switches. This stops the blade from firing accidentally in your pocket.
Important Materials Matter
The materials used determine the knife’s strength and how long it lasts.
Blade Steel
The steel needs to hold an edge and resist rust. Good options include:
- D2 Steel: This is a tough, common choice. It holds an edge well but needs some care to prevent rust.
- CPM-S35VN or Higher: These are premium steels. They resist rust much better and stay sharp for a very long time. They cost more, though.
Handle Construction
The handle holds the whole mechanism. Look for strong, light materials:
- Aircraft Aluminum: This is the standard for quality OTFs. It feels solid and keeps the weight down.
- G-10 or Polymer: Some handles use these strong plastics. They offer a good grip, especially when wet.
Factors That Improve or Reduce Quality
Not all OTF knives are made equal. Small details change the overall quality.
Action Smoothness
A high-quality OTF knife opens and closes without sticking or grinding. You should hear a satisfying “click” when it locks. A rough action usually means cheap internal parts are used.
Fit and Finish
Check how the handle pieces fit together. There should be no gaps or wiggle in the handle. Poor fit often means water or dirt can easily get inside and break the springs.
Tolerances (How Tight Parts Fit)
Tight tolerances mean the moving parts fit together perfectly. This is key for reliable firing. Knives with loose tolerances jam more often.
User Experience and Use Cases
Think about why you want the knife. This affects the size and style you should buy.
Everyday Carry (EDC)
For carrying daily, choose a smaller, lighter knife. A blade length between 2.5 and 3.5 inches works well. Ensure it has a strong pocket clip.
Tactical or Collection Use
If you need it for emergencies or want a display piece, you might choose a larger, more robust model. Double Action (DA) knives are preferred here because they deploy faster under stress.
Always check your local laws before purchasing or carrying any OTF knife. Laws about these knives change depending on where you live.
10 Frequently Asked Questions (FAQ) About OTF Knives
Q: Are OTF knives legal everywhere?
A: No. Many places ban automatic knives or restrict blade length. Always check your city and state laws first.
Q: What does “Double Action” mean?
A: It means the knife fires out and retracts back into the handle using only the main firing mechanism, usually with one button press in each direction.
Q: Why are some OTF knives so expensive?
A: High cost usually comes from better materials (like premium steel), tighter manufacturing tolerances, and more complex, smoother internal actions.
Q: How do I clean an OTF knife?
A: Keep the mechanism clean and dry. Use compressed air to blow out dust. A tiny drop of high-quality knife lubricant on the tracks can help keep it smooth.
Q: Can I sharpen an OTF blade myself?
A: Yes, you sharpen the edge just like any other knife. Be careful not to push too hard, which could damage the tip.
Q: What is the most common handle material?
A: Aircraft-grade aluminum is the most common material for good quality OTF handles because it balances strength and weight perfectly.
Q: What is a “blade play” issue?
A: Blade play means the blade wiggles slightly when it is fully locked out. Good knives have almost no blade play.
Q: Should I get a single-action or double-action knife?
A: If you want speed and convenience, get a double action. If you want simplicity and lower cost, a single action is fine.
Q: How often should I oil my OTF knife?
A: If you use it often, check it monthly. If it sits in a drawer, check it every few months to ensure the springs do not seize up.
Q: What size blade is best for daily tasks?
A: A blade between 3 and 3.25 inches is usually the sweet spot for cutting boxes and opening packages while staying legal in most areas.
