This is my first visit here, Hi Everybody, I have a collection of blades from my dad's old switchblade to some of Daniel Watsons swords. Bought my first butterfly knife in 1979 "Manilla Folder" (learn how to work one before you sharpen it:). I have been playing with sharp objects since I was three and I still have all my fingers and toes.

I found this site while searching for some help/solutions to the problem I have had with the last two Puma Packer lock-backs I got. After about four month of carrying and use, the locking mechanism disengages with little pressure, I have cleaned, scraped, oiled, cleaned again with no improvement. I do not abuse my knives, and had never had trouble with the first Pumas (same model) that I bought in the early 1980's. I would take it apart and "tune it up", but don't really have the know-how to put it back together "good as new".

I like this model and it has been dependable in the past when I worked offshore as a commercial diver, and climbing poles and towers as a lineman.
The steel, weight, blade and handle shape make it a perfect companion for my lifestyle (and if the need ever arose, self-defense).

I could go on about my love affair with sharpened steel, plenty of time for that, I could really use some advice, if not just a shoulder to cry on :).
 
Welcome to BF!

I don't have a lot of experience with lockbacks but you might check the part of the lock bar that goes into the tang and see how much steel is left. It may be that the bar is engaging the tang there's just not enough steel to keep it there. I'm sure someone much more knowledgeable that myself has a better solution...
 
All my Puma lockbacks are older models, and they are all pinned construction, so I'm not sure how much help I can give you. It sounds like a loss of spring tension on the lockbar spring, which would require disassembly to repair, and new pins to reassemble the knife. No offense, but that is not a job for the average Joe. I suggest checking with Puma for warranty first. If that doesn't get you anywhere, there is a forum member here called STR who does a lot of repair/rebuild/customizing work who might be able to help.

Good luck, and welcome to the forum!
