I purchased a double edged satin blade infidel. Upon getting it home and checking it out further, it failed to retract and eject about 20% of the time.

So I cleaned it out with compressed air and used a light/very thin lubricating oil in it. After that, no more malfunctions...

Except that when the knife is on it's side or upside down, it fails to retract completely. I do not have this malfunction when the knife is in the upright position.

I'll send it in for repair.

I had mine for 1 year and never had single misfire or failed retract. I used it almost every day. Defective model?

I’ve never had a problem w mine, and I demand perfection from my knives-

the lubricant that I use on my manual & auto knives is Break Free CLP-

some eye candy

I had trouble with mine at first,and to find out it was the lubricant that i was using.So i just washed it out a few times,and have had no troubles since..Like Auto_luver says..You will need the right kind of lube.It seems BM's OTF auto's are weak springs or to sensitive for most lubes..

I dont have a problem using any kind of oil on my infidels. I use regular old 3 in 1 oil and mine work perfect, even when I carry and use them. Ive had grit and lint in them and they still work.

Yeah, it must be a defective model. I sent it in today for repair or replacement.

let us no the turn around time..

Got it back today. 10 days total turnaround including shipping. Seems to be working fine now.
