1. Use the Right Knife Cleaning Tools 

You need a few things to do the job right. To begin with, you want to use a quality knife lubricant. For example, you should use gun oil, Rem oil, or WD-40. 

You also want to use a clean, soft rag to remove any debris. Finally, you need a precision screwdriver to disassemble and reassemble your OTF knife.

2. Discharge the Blade Before You Begin 

Remember to work safely when cleaning your double action knife. It’s a good idea to discharge the blade before you start to maintenance it. Fire it at close range against something that you don’t mind scuffing up, such as a piece of scrap wood. 

When the tip of the knife hits the object, it will discharge from the sliding mechanism. 

If you do it right, you can move the handle in out of the blade freely. Also, the blade won’t accidentally fire or retract.

3. Clean Your Double Action Knife Often 

You need to clean your OTF knife more than once a year. Clean it regularly for optimal performance. 

You should clean your double action knife immediately after you use it. Coat the blade with lubricant and wipe it off to prevent residual buildup and rust.

4. Know the Signs of Trouble 

There are a few signs that will show you that your OTF knife needs maintenance if you haven’t serviced it regularly. For instance, it may misfire when you pull the trigger. 

Also, it may feel sluggish when you fire the blade. Additionally, the blade might discharge slowly. You also want to clean your double action knife if you see residue clogging the opening.

5. Touch It up In-Between Servicing

For in-between cleanings, use compressed air to blow away lint or other loose debris. If you’ve somehow transferred adhesive backing to the blade, you can remove it with 99% Isopropyl rubbing alcohol and a Q-tip. 

Also, spray lubricant onto the blade and let it run down inside the handle. Fire and retract the blade a few times to lubricate the internal parts, then blow it out once more with compressed air to remove extra oil.

6. How to Store Knives 

Keep your OTF knife covered and away from dust and moisture. By protecting your knife, you’ll reduce clogging and rusting. 

If you carry your OTF knife every day, use a carrying pouch. The pouch will protect it from residue and reduce the number of times that you need to service it.

7. Reassembling Your OTF Knife 

It’s always easier to disassemble something than it is to reassemble it. No worries. Here’s what to do in case you have trouble reassembling your knife. 

It’s relatively easy. There aren’t many double action knife components.
