Is My Knife Broken or is it Just an OTF?

Is my OTF Knife Broken?

Is My Knife Broken or is it Just an OTF? 

If you’re new to the OTF world you may have noticed that there are tons of OTF knives to choose from. Different handles, sizes, blade material and shapes, single action, double action, and this list goes on and on. What do all these OTF’s have in common? A safety feature. A safety feature that if you are new to owning an OTF knife, may make you wonder if your OTF knife is broken. 

We love first time buyers. We love introducing them to the wild ride of what owning an OTF knife has to offer.  Yes, your friends do want to see your new knife. Yes, it is fun to deploy and retract, deploy, and retract, rinse and repeat. And of course, it is handy and durable and can easily be your daily EDC knife.

However, part of that introduction is getting the e-mail that a first-time purchaser and owner believes that their OTF knife is faulty and/or broken when in reality they just haven’t experienced or understood the safety feature that OTF knives have.

This is where we at TacKnives explain it, in hopes you can read this before we get the e-mail.   

Just like your favorite firearms have safeties, so does your favorite OTF knife. Here is how it works: 

For safety reasons your OTF knife (no matter which brand you get) will not puncture through anything on deployment. When your blade is pressed against a surface, and you deploy the blade, the resistance in deployment against the blade will trigger a safety. The blade will instantly become loose and slide in and out of the handle freely without resistance.

*It is at this point we get the e-mail saying that the knife if broken*

To re-set your blade, pull the blade all the way out until it clicks into place. At this point, your knife will perform the same as it always has. 

To answer the question at hand, your knife is not broken, it’s just an OTF.
