Test Your Tactical Folding Knife

*Please note, it is YOUR responsibility to know and understand the laws regarding carrying a knife and or using it for self defense purposes. Use caution when handling any knife. This post and video are for information purposes only. 



Test Your Tactical Folding Knife


A folder is a “broken” knife. It’s only as strong as the lock open mechanism. Test the lock of every new folding knife.

If its a “tactical folding knife” that may be used to defend life then having confidence in that knife is essential. It’s bad enough if you have to use it for that purpose. Things will be even worse if you lose fingers in the process.





This particular knife is not advertised as a “tactical folder” but if it’s being carried could it be used for defensive purposes?


Note in the video how close to the inside edge the liner lock is when in the locked open position. What does this mean? Is the knife faulty? Will it close on my hand?



That depends on what you will be doing with the knife. If cutting and pushing away from yourself, like with many everyday uses, then it should be fine.

Spine of Knife


You are pushing against the spine of the knife in the direction it goes to be locked. If it fails the unsharpened spine may hit the hand.



Thrusting or stabbing into something is a different matter.
Consider thrusting into something that may have an unexposed hard surface. Like an attacker in an effort to get them away from you and or keep them away from you. Hard bone lies beneath soft skin.


The “spine whack” test seen here isn’t representative of any tactical use of a knife. It’s far from scientific. But, I’ve thrusted live blades like this into cardboard targets while practicing and impacted the wooden 1×2 upright holding the target. The angle of the point upon impact was off just enough to cause the lock to jump and close.


This has happened to me with a few different folders. I now use the spine whack test on every new folder. If you’re gonna try this test; watch your fingers. The blade can move fast and far depending on how much force you use.


Final Thoughts

Want to eliminate this problem altogether? Get a small fixed blade. Just kidding, I like my folding knives as much as the next guy. Just be aware and plan accordingly. You never know what you may have to use that knife for.

    Good advice, I just tested my two edc folders and they passed. Thanks for looking out for us. Gary

  2. I tested my Griptilian against a 4 x 4 fence post. A fixed blade would have been jealous. Of course, it uses the Axis lock. I like a fixed blade, but this knife is much easier to carry almost anywhere.
