All About Pocket Knives

I found this PK-2 awhile back, decent price, pretty good shape.
I bought it with the intention of fixing the linerlock, and haven't got around to messing with it til now.
This little project intimidates me some. I know me, I can tear stuff up so good it ain't fit for the job yard. I kinda don't want that here.
I know theres quite a few very good mechanics here, just looking for a little advice.

Hey Alowishus Devadander Abercrombie - It's hard to tell exactly what is wrong with it. Any way you can post a picture with the knife at a couple of different angles?
